My Baguette Dough Development Process

This morning, I was thinking about the several different types of techniques of baguettes that I make: Pointage en Bac, Baguettes de Tradition, Poolish, Levain, Poolish, and Sourdough, Sourdough and Yeast; not to mention varying the hydration and flour blends to achieve different textures. The baguettes pictured above are Poolish and Levain baguettes ala Tartine Bread. They’re a low hydration double preferment bread that produces a crunchy crust and a chewy crumb. My Baguettes de Tradition on the other hand create a light, crispy crust with a light, airy crumb.

In any case, I realized that I use two dough development techniques depending on the type of rising agent I use: One for yeasted and another for sourdough. So I thought I’d share them here so I could just link to them in my future baguette recipes as I’m tired of duplication.

Flour Type

People ask me what flour I use for making baguettes. Traditionally, baguettes are made with white flour. But unless I’m teaching a basic technique or introducing a new recipe, I invariably use a mix of different kinds of flour to affect different flavor profiles in my bread.

Sift Your Flour!

Whether or not you use a blend of different flour, you should always sift it before mixing. This will prevent large lumps from forming during the mixing process.

Yeasted Baguette Dough Processing

Mix. Mix all the ingredients together to form a shaggy mass. With my yeasted dough baguettes, I normally don’t do an autolyse.

Bulk Fermentation. 1 1/2 to 2 hours or 6-18 hours in the fridge. Bulk fermentation is finished when the dough has expanded about 50%.

Folding. Whether doing a cold bulk fermentation or not, stretch and fold the dough every 20 minutes in the first hour. By the third fold, the dough should be smooth and luxurious and will be highly extensible.


Levain Baguettes

Whether I’m making a double-preferment (both poolish and levain) or just a straight levain dough, I use the same process for both, which leans heavily on Chad Robertson’s dough development technique.

Initial Mix. Reserve 50g of the water and set it aside. In a large bowl, dissolve the preferments(s) into the remaining water to create a slurry. Add the slurry to the flour and mix until no dry ingredients are left and you’ve formed a shaggy mass. Cover and allow to rest 30-60 minutes.

Final Mix/Bassinage. Sprinkle the salt over the dough, then add the reserved water to the bowl. Work the salt and water thoroughly into the dough until all the water is absorbed and you can no longer feel any grittiness from the salt.

Bulk Fermentation. 3-4 hours @ room temp. Bulk fermentation is complete when the dough has expanded about 25%-30% in volume.

Folding. Fold up to 6 times every 30 minutes for 3 hours. That said, really feel the dough and check its extensibility before each folding session. This folding schedule is based on the Tartine method which calls for 6 folds over 3 hours. However, I’ve rarely gone past 4 folding sessions with the flour blends I use – they get strong real fast, even if I’m handling them gently!

Once you’ve built up dough strength, you can either proceed to shaping or pop the dough into the fridge for further flavor development from 8-18 hours.


Both Yeasted and Levain Baguettes

Divide and Pre-Shape. All the baguette recipes I post here either make 4 X 335g baguettes or 6 X 220g baguettes. Whichever you choose, divide the dough into pieces of that weight. Once divided, letter fold each piece by stretching one side, then folding it to the center, then stretch the other side and fold it over the body of the piece. Then roll the piece up like a jelly roll perpendicular to the folds, seal the seam, then place the piece seam-side-up on a well-floured couche.

Shape. I use Master Chef Markus Farbinger’s shaping technique. There are others out there, but this is the one I know. Feel free to use one with which you’re familiar.

No matter the shaping technique you use, bear in mind that shaping a baguette is not just rolling the dough into a long, skinny log. The first part of getting it into a cylindrical shape builds skin tension prior to rolling it out. This is absolutely critical to achieve ears on your cuts when you score! I will submit that this particular step is the most important step of shaping.

Final Fermentation: Depending on the ambient temp of your kitchen, final fermentation can take anywhere from 30 minutes for yeasted baguettes to 2 hours for levain baguettes. In either case, to determine when the loaves are ready for the oven, poke a floured or wet finger about a half to three-quarters of an inch into a loaf, then pull your finger back quickly. Observe the rate at which the indentation comes back. If it doesn’t come back at all, pop the loaves into the oven immediately – you’re extremely close to over-fermenting the dough. If it comes back quickly, and almost fills the indentation back up, give it a bit more time. If it comes back quickly, but immediately slows down, then you’re ready to bake!

Scoring. Scoring should be done in the middle third of the loaf, using fairly straight lines that overlap each other by about a third. The lame or scoring blade should be at an extreme angle to create a flap which will in turn bake into an ear as seen in the picture below.

Don’t cut across the loaf! This will only create diagonal slashes!

Though Chef Markus mentions overlapping the scores, he doesn’t discuss why you need to do it. If you don’t overlap the scores, your baguettes will indeed open at the scoring sites, but they’ll come out as bulges and remain narrow where the cuts didn’t overlap, so the sides of your baguettes will be wavy, not straight.

Baking. Bake at 475ยบF with steam for 12-15 minutes or until the loaves start taking on color. Vent the steam and remove your steaming container, then bake for 12-15 minutes at 425ยบF or until the loaves turn a nice, deep, golden-brown.

Alternative Baking Method. Bake at 400ยบF for 20 minutes with steam. Remove the steaming container, then finish baking at 425ยบF for 25-30 minutes. I know it sounds backward, but it actually works great!

Baguettes based on the Tartine Bread recipe.

Poilane-Style Pain au Levain Using Double-Fed Levain

I’ve made no secret that much of what I bake is heavily inspired by traditional and ancient French and Italian bread. There’s a certain romance to it all and as a hopeless romantic, making these kinds of bread have a deep appeal.

But despite my love of ancient bread, my dough development techniques are all influenced and inspired by studying modern baking masters such as Markus Farbinger (Il de Pain, Knysna, South Africa), Jeffrey Hamelman (Director of Baking, King Arthur), Chad Robertson (Tartine Bakery, San Francisco), Carol Fields (Author of “The Italian Baker”), Nancy Silverton (Founder, La Brea Bakery, Chef & Restauranteur, L.A.), and Paul Barker (Cinnamon Square Bakery, UK)… which brings me to this particular recipe.

Asked to think about French bread and most people will immediately think of baguettes or the thicker long loaves labeled “French Bread” in the grocery. Long loaves made of white flour seem to have become synonymous with the country. But the baguette, while much loved (if you read this blog, you know how much I love to make baguettes), isn’t that old – at least relative to the traditional bread – having only been introduced in the early 20th century when bakers started using brewers yeast to leaven their bread. Before that, like hundreds of years before, naturally leavened bread ruled.

This particular bread really is a melding of the ancient and modern. While it’s a pure levain bread I use what Chad Robertson calls a young levain that provides a very light tartness as opposed to being strongly sour, which explains why I feed the levain twice in one a day prior to mixing (plus it’s highly active to give a good rise). The base of my starter uses employs a yeast-water culture I learned from Paul Barker’s Naturally Fermented Bread. And the recipe leans heavily on Hamelman’s Pain au Levain in Bread. Bread is so cool…

Build the Levain

With this levain build, there’s no discard, save for what’s leftover from the build which you can pop into the fridge and use later. The thing about this levain is that it’s young and the way it’s prepared promotes yeast growth over bacterial growth. Traditional French sourdough has a tang but is not sour, so we focus on the yeast with this kind of levain.

Initial Levain Build. Add 25g mature starter (I just take it directly from the culture in my fridge) and add it to 50g flour and warm water, respectively. Allow doubling in volume with a slightly domed top and lots of bubbles. The build’s ready when it passes the float test – about 3-4 hours.

Second Levain Build. Add 75g of each flour and warm water to the levain. Mix thoroughly and let ferment. It should be ready in just a couple of hours – or even less. The levain is ready when it passes the float test.


If you’re working from home: Timing-wise, you could start the build early in the morning and mix before mid-afternoon.

If you have to go into the office: Do the first build immediately before leaving for work and leave it in a cool place. By the time you come home, the levain will have peaked and collapsed – that’s okay, but it’ll be pretty sour. You can discard a bit of if you don’t want the bread to be too sour. I myself just keep it all. But to help counteract the sourness, I use 100g of each flour and water. You’ll mix by early evening then shape right before bed. Then you can bake as soon as you get up!


Make the Dough

Initial Mix/Autolyse. If you’re using a flour blend, mix the flour until well-combined. In a separate bowl, measure out the levain you’ll need, and dump in all the water. Dissolve the levain until you have a thin slurry. Pour the slurry into the flour, then mix until no dry ingredients remain. Rest the mix for 30-45 minutes.

Final Mix/Bassinage. Sprinkle the salt over the dough, then add the 50ml of water. Work the salt and water into the dough until thoroughly combined.

Bulk Fermentation. About 2 1/2 – 3 hours, or until dough has risen to 50% of its original volume.

Folding. Fold twice at 50-minute intervals.

Shape. There’s no preshape with this bread! Gently turn the dough out onto a lightly floured surface, then divide into 900g pieces. Shape the pieces into tight rounds then place them into linen-lined baskets.

Final Fermentation. 1 1/2 – 2 hours @ room temp, or pop into the fridge for 6-12 hours.

Bake. Bake at 440ยบF 45-50 minutes. Bake with steam for the first 20 minutes, then finish the bake with a dry oven.

Coming Clean…

Though I provided a recipe here, it’s really meant as a guide to enable you to freestyle later which sort of explains why I didn’t take much space with the more verbose explanations I usually provide. In fact, with the loaves at the top of the article, though I did measure out the ingredients so I could prove out the formula, I freestyled the process.

I had to because now that I’m going into the office three days a week, my baking time is limited. With the levain build, I actually did start the first build before I left for the office. And though I stored it in the coolest part of my house, by the time I got home, it had peaked and collapsed into a pleasingly sour mass. But I just fed it – and my instinct told me to use a higher ratio of flour and water and not just do a 1:1:1 so I probably used a 1:3:3 – and the microbe density was so high at that point that the second build was ready in just over two hours!

That’s the whole point of calling this a “Poilane-style” bread. At the famous Poilane Bakery in Paris, bakers make their famous miche relying purely on instinct. They go through a year and a half apprenticeship to learn the technique so well that they can pretty much eyeball the whole process. For me, baking by pure instinct is the ultimate expression of being a bread baker, but also the most pure form of historical expression, if you will.

Think about it. Back in ancient times, they didn’t have digital scales and temperature gauges. Bakers just relied on their senses. They took a little bit of this, a little bit of that and they just instinctively knew when to move on to the next step. So if and when you make this bread, pay attention to the look, feel and smell of the dough as you develop it. Then the succeeding times you bake, rely less and less on the recipe. You’ll actually be pleasantly surprised at how much you retain.

Batard Using Whole Wheat Poolish (Updated)

The loaf above just came out of the oven about 15 minutes ago as I write this recipe! This was a free-form batard where I didn’t use a banneton and proofed on a couche!

I love making bread from a poolish – or sponge – before I go to bed, then make a couple of loaves the next day. With this recipe, I’m using 25% fine-ground white whole wheat flour. You can use red whole wheat as well, but just make sure it’s fine-ground or extra-fine ground.

I will be upfront: It’s going to take a bit of patience, especially after mixing the final dough because there’s very little yeast used in total (I kind of wanted to simulate sourdough dough development). But your patience will be rewarded with a slightly sour bread with a wonderful, light, chewy texture. I did my folds in between meetings today! And the bulk ferment took about 5 hours. So yeah… it takes patience. Without further ado, let’s get to the recipe!

Make the Poolish

Just-mixed poolish, ready for a long nap.

The evening before you bake, in a large bowl, mix up the ingredients for the poolish until everything’s incorporated. Make sure to scrape down the sides of the bowl with a spatula. Cover the bowl with plastic wrap, making sure it vents to release the gases. Let it sit and do its magic for 12-16 hours. If your kitchen is really warm like mine, 12 hours is the max! But please do not rely on time! What you’re looking for is the poolish being bubbly and slightly domed on top. It should pass the float test (see picture below).

Tip: Alternatively, you can pop the poolish into your fridge and let it develop for 18 to 24 hours. I’ve found that this actually mellows the sourness a bit, but introduces some interesting nutty and earthy notes. NOTE that if you decide to do this, let your poolish “wake up” for an hour at room temp before doing the final mix.

Poolish is ready and passes the float test.

The Next Day ~ Mix and Bulk Ferment

Measure the temperature of your flour. We’re after around 75-80-degrees of final dough temperature. Use the following table to determine the temp of your water:

Flour TempWater Temp
55110
60100
6590
7080
7570
8060
8550

Add the rest of the water, salt, and yeast to the bowl with the poolish and mix thoroughly with a dough whisk or fork until the poolish is fully dissolved. Once combined, add the bread flour in batches.

Using a Danish dough whisk makes quick work of bringing ingredients together. That was probably one of the best investments I made for baking bread. By the way, that’s a 24″ wide mixing bowl. I prefer mixing in a huge bowl like that because it makes mixing by hand much easier as I don’t have to worry about ingredients popping out of the bowl!

Form the dough into a rough ball and let it rest in the bowl for 10 minutes. After 10 minutes, fold the dough, then turn it over to rest on the folds. From there, fold the dough every 30 minutes for the next 2 hours or until you feel the dough is strong and extensible (hint: do the windowpane test to see if it is developed enough). Other than the windowpane test, I know the dough has developed enough strength if I can take 1/4 of the dough ball and stretch it up about a foot without it tearing. But bear in mind that as you are using whole wheat flour, you need to be gentle when handling the dough!

I use a 6-liter Cambro container for bulk fermentation.

Finally, cover the bowl and let the dough rest for 2 hours or until it has expanded about 25% to 30% in volume with a nicely domed top. You may not see bubbles on top, but that’s okay. Give your container a gentle shake. The dough should be jiggly, which means there are air bubbles in the dough, which is what you want! If you don’t see much growth, and the dough’s not very billowy, just give it more time.*

Tip: Turn on your oven to 475 before dividing and shaping. If you’re cooking on a stone, make sure it’s placed on the middle rack and you also place a metal baking pan (I use a sheet pan) on the bottom rack. You’ll be pouring a cup of hot water into the pan to create steam.

If you’re using a Dutch oven, place it in the oven now so it’s hot when you’re ready to bake. A steam source isn’t necessary for the Dutch oven since the baking bread will provide enough steam in the enclosed chamber.

*Notice that I didn’t say wait until doubled. The whole doubling in size that you often see is a little misleading. Most recipes, even some of my early recipes, give that as a telltale. But to be honest, if you let your dough fully double or even triple in size, chances are that you’ll end up on, or close to the very end of the fermentation cycle where the yeast and microbes have no fuel left for the final fermentation. This is why I mentioned inspecting the dough to see if it’s jiggly (which means there are air bubbles in it). I’ve learned to rarely let the dough go over 50% expansion in volume unless I will be shortening the final proof.

Typically, you’ll see a double in size telltale with quick bread, or bread that is baked within a few hours. Those typically have a fairly short final fermentation. But with this particular bread, we’re only using a very small amount of yeast, so dough development is much more akin to sourdough as the rising process is much slower.

Divide and Shape

This is a fairly high-hydration dough at 75%. It’s not impossible to work, but it can be a bit challenging, especially if you haven’t worked with dough at this hydration rate. Anyway, pour your dough out from the bowl and divide it into two equal pieces. With this recipe, they should weigh ~880 grams each. Preshape into rounds.

I learned how to pre-shape and shape high-hydration dough with the following video:

I use a different batard shaping method that can be viewed here.

Final Proof

Once you’re done shaping, place the dough in an appropriate proofing container (banneton, wicker basket, etc.). Proof the dough for an hour or two. But check it after a half-hour with the finger dent test. On especially warm days, my dough proofs quickly.

Tip: For smaller batards, I got some french fry baskets to use as bannetons that work great. I also did an 18-hour proof in my mini-fridge, set to about 40-degrees to do a slow proof. Frankly, if you have room in your fridge (or a second fridge to use as a dough retarder like I do), I’d recommend doing a slow, chilled, final ferment. Cold dough is much easier to slash and also, even more importantly, cold dough releases steam into the bread for a longer time, promoting better oven spring.

Alternatively, you can shape these into logs, and instead of placing the dough into bannetons, place them into loaf pans. This recipe makes excellent sandwich bread!

Bake

Once proofed, place the dough on a peel or appropriate device to slide onto your stone that has been liberally sprinkled with cornmeal or flour if you don’t have cornmeal. Don’t be shy about it! Your dough has got to slide off the peel easily. ๐Ÿ™‚ But before you place the dough into the oven, score it with a super-sharp knife or a lame. Slide the dough onto your stone. Immediately pour the cup of hot water into the baking pan below. Careful of the steam that will rise!

If you’re using a Dutch oven, remove the Dutch oven from the oven and place it on a heat-safe surface. Remove the cover, then place your dough directly into the pot. Cover and place back into the oven.

Bake at 460 for 40 minutes or until the crust achieves the classic tri-color of a deep burnished brown, golden in the cut groove, and blackened at the tips of the ear. Remove the baking pan from the oven after 20 minutes. If you’re using a Dutch oven, remove the lid after 20 minutes and bake open for the last 10 minutes.

That’s it! Enjoy!

Master Chef Markus Farbinger’s Ciabatta Recipe (Updated)

No way am I going to take credit for developing this recipe, though I have made my own tweaks to the flour. The recipe comes from master chef Markus Farbinger. I had no idea who he was until I happened to stumble on his baguette shaping video on YouTube. His technique was so incredible that I ended up buying his baguette and ciabatta video series on Vimeo. This ciabatta recipe is from that series.

To be honest, even though I’m documenting the recipe, I’m really only scratching the surface. I highly recommend renting or purchasing the series. Chef Markus the former Dean of Curriculum and Instruction for Baking and Pastry Arts at the Culinary Institute of America, and is co-owner of the Ile de Pain bakery in South Africa where he uses a wood-fired oven to bake his artisan bread. In other words, this dude is totally legit!

Overview

Like traditional baguettes, this ciabatta uses a poolish that you make the night before you bake, then in the morning, you mix the final dough. With this particular recipe, the process is quick! I mean, real quick. Things happen much faster than with your typical artisan loaf. Once you mix the final dough, your loaves are in the oven within an hour-and-a-half!

On top of that, you only manipulate the dough three times before baking and two of those times are devoted to creating structure. So you really only have two opportunities to create structure and strength in your dough before you bake. That third time is just pushing the dough into a loaf shape and transferring it to a couche. There’s no formal shaping and scoring with a ciabatta. So you have to get the structure-building steps down!

Now don’t go thinking that this is a beginner’s bread simply because of the short prep time or the use of commercial yeast. It isn’t. What makes it difficult is the hydration rate is a whopping 85%! At that level, it’s almost like working with a batter, and even for seasoned bread makers, that kind of hydration rate can be a little daunting. So like making baguettes, making a great ciabatta is less about the ingredients and so much more about the technique.

The Recipe

If you read the recipe table, you won’t see any olive oil. The only time it is used is to coat the mixing bowl after the second fold, just prior to the final fermentation. I’m not sure why this is, but the results are pretty marvelous just the same.

Like baguettes, the process occurs over two days. You create a poolish the night before, then mix the final dough and bake in the morning.

Overall Formula

I’m providing the overall formula because it is possible to do this as a straight dough.

Mix all the dry ingredients together, then add water in batches until you form a smooth, thick batter. Set aside at room temperature for 12-16 hours. I shoot for 14 hours. As an early-riser, I make the poolish at about 4pm then mix the final dough at 6am the next day.

If you’re using yeast packets, simply take a healthy pinch from a packet to use for the poolish, then use the rest for the final dough.

Final Dough – Day 2

FlourWaterSaltYeastPoolish
500 g Bread Flour350 ml20 g6 g1000 g
– If you’re wondering if the amount of yeast listed seems to be a bit much, bear in mind that Chef Markus uses 15 grams fresh yeast. The instant/active yeast equivalents are 30-40% of fresh yeast.

Dough Temp: 475F/24C

Before you start, I recommend using a round-bottom mixing bowl for the fermentation steps. The dough is so wet that it will be difficult to do stretch & folds if you use a vertical-sided container. Also, a couche is very helpful to have, especially for the final proof.

Note that the times listed are approximate! I just baked a batch yesterday and because it was early in the morning and very cool, I had to extend the times to 30 minutes, and I let the final proof go for 20 minutes.

Mixing. Sift the flour into a mixing bowl, then add the salt and yeast. Use a whisk to combine and thoroughly incorporate all the dry ingredients together. In a separate bowl, combine the poolish and water and completely dissolve the poolish. Once it’s liquified, pour the liquid into the mixing bowl and mix until no dry ingredients are left. Mix into a shaggy mass, then let the mixture rest for 20 minutes.

You can use a stand mixer for this step, but with this small amount of dough, I just mix by hand and use a Danish dough whisk. It’s pretty fast with this kind of hydration.

Bulk Fermentation First Fold. After the dough has rested, do a series of stretches and folds in the bowl. The trick to folding a super-wet dough like this is to make your hand like a wooden spoon, with your fingers pressed together. Scoop from the side and slip your fingers under the mass, then lift. At first, most of the dough will kind of pour out of your hand, but as you stretch the dough more and more, you’ll feel the tension building and the dough won’t pour out nearly as much. Wet your hand regularly! Once you feel as if you can pick up about a third of the dough mass when you scoop, you’ve built up enough strength for that session. Cover the dough and rest for another 20 minutes.

At this point, it’s a good idea to start preheating your oven (to 475ยฐF/250ยฐC), especially if you use a baking stone like I do.

Bulk Fermentation: Lamination. Generously flour your work surface, and I mean generously, then pour out your dough onto your work surface. Check to see if you can lift up the edges of the dough, and use your bench scraper to push flour under areas that are sticking. Gently tug the dough into a square, then starting at the bottom edge, quickly work your fingers under the dough (your fingers should be pressed together, give that side a stretch toward you, then fold the edge about 2/3 over the dough. Do the same with the top edge. Once you’ve folded the top edge over, gently pat the dough down to even out its thickness, then fold the left and right sides. Gently pat down the folded dough, then repeat the process.

Chef Farbinger laminates his dough 3 times. But with the King Arthur AP flour I use, by the time I’m finished with the 2nd lamination, the dough is nice and strong. Not matter what, once you’ve finished lamination, Roll the dough onto its seams then form it into a round. Place the dough into a well-oiled bowl (I just rinse out my mixing bowl then spray oil in it). Let the dough rest for 20 minutes.

Divide and “Shape“: Flour your work surface again, but not nearly with as much flour as with lamination. Slide the dough ball into the surface. Then using your bench scraper, gently tug the dough into a rectangle with fairly even thickness. Cut the dough down the center along the long edge to form two “slippers.” Then work each piece into long rectangles. Picking the loaves up from the ends and scooping towards the middle, transfer the loaves to a well-floured couche or tea towel. Lightly flour then dimple the tops to even out the thickness.

Final Fermentation: 10 minutes

Bake. If you’re baking on a stone, transfer the loaves to a loading board generously sprinkled with cornmeal. If you don’t have a board, cover a baking sheet with parchment paper, then sprinkle cornmeal on the parchment paper. Bake the loaves at 475ยฐ-480ยฐF (~250ยฐC) with steam for 15 minutes. Remove steaming container(s), then turn down the oven to 400ยฐF (200ยฐC) for another 15-20 minutes or until the crust turns a deep golden brown. If you want to follow tradition, don’t bake your loaves past this as the standard crust thickness should be 3mm on average according to Italian law. But that said, bake the loaves to whatever doneness you want!

I put “tradition” in italics above because technically ciabatta didn’t exist until the early 1980s. However, the technique is steeped in thousands of years of tradition.

Sourdough Ciabatta

After the success I had with the baguettes based on the Tartine Bread recipe, I thought I’d apply a similar principle to making ciabatta. But this time around, roughly 30% of the flour would come solely from a young sourdough starter as opposed to the half levain/half poolish of the baguettes.

Notice that I mentioned employing a young sourdough starter. This is important in that I wanted lots of yeast activity and also to mitigate the sourness from the bacteria. This is along the lines of Chad Robertson’s approach in Tartine Bread.

Like all ciabatta, this is an extremely wet dough. When you fold this dough the first time, it’ll feel a little icky. But don’t worry. The results are fabulous! Let’s get into the formula.

Please TRUST YOUR EYES AND YOUR HANDS with this. I list out times like 30-60 minutes, but things can happen faster or slower. As with any baking process, times are only guidelines!

Make the Levain. I do a double feeding to really crank up the yeast activity before I mix the dough. So I first take a good spoonful of mature starter and add that to 100g of AP flour and 100ml of water and mix it up well. I place my container in a fairly warm place (80ยฐF+) and let it more than double. When it’s ready, the top is bubbly – very bubbly – and you can see the activity of the yeast. Once it gets to that point which, at least for my starter, takes about 2-3 hours, I feed it with 100g flour and water, then let that double. The activity is pretty strong at this point, so the levain is ready in under 2 hours (yesterday, my levain was ready in an hour!). The levain will be fairly bubbly and as with the initial feeding, you should see activity at the top of the mass.

Initial Mix. In a large bowl, mix the levain and all of the water and completely liquify the levain. Place the flour in another large bowl, then gradually add the water and mix until there are no dry ingredients. Rest for 30 minutes.

Final Mix. Sprinkle the salt over the dough mass, then once lightly incorporated into the dough, add the olive oil. It’s best to just squeeze it into the dough to work it in. Once all the olive oil is incorporated, do a series of light stretches and folds to fully incorporate the salt and oil. Note that this isn’t meant to build strength in the dough. Rest for 30 minutes.

Bulk Fermentation. Up to 2 hours depending on ambient temp. Ideally, your dough should ferment in an environment that’s no lower than 78ยฐF.

Folding. After 30 minutes, stretch and fold the dough. It will be wet and will feel like a batter. Continue stretching and folding until you start feeling some tension build in the dough. You may have to do 10-12 stretches and folds. Four will not do the job. This is a critical step in building up some dough strength and gas retention properties in the dough. I love this part because I can literally feel it transform from a very liquid mass into a dough. After folding, rest for 30 minutes.

You may not see much apparent fermentation activity at this point, but that’s okay. The yeasts are working!

Lamination. This is the last step in building structure in the dough, so it’s pretty important. Liberally flour your work area. Don’t be stingy with the flour here because you do not want it to stick and tear the dough. Using your bowl scraper pour your dough out onto your work surface. Then to ensure that there’s flour underneath your dough, use your bench scraper to push flour underneath any areas that could potentially stick. To make sure your dough’s not sticking, move the whole mass around. It should move easily. Then once you know it’s not going to stick, with quick, definitive motions, slide your fingers under the sides of the dough and lightly stretch it into a square till the dough is about 3/4″ thick.

Take the top of the dough and stretch it away from you a bit and bring it to the center. Take the bottom half, pull it toward you, then completely overlap the top fold. Gently pat the rectangle down to even out the thickness, then do the same stretch on the left and right sides. Pat the dough down, then repeat the process two more times if you can. If the dough fights you, that’s a good thing. It means you’ve built some strength into the dough. Once you can no longer laminate the dough, gently roll it onto the seams and with cupped hands, work it into a round. Transfer the round seam-side-down into a lightly oiled bowl. Let the dough rest in the bowl for another 30 minutes or until you see about a 25% increase in volume. Note that this could take a little longer.

At this point, preheat your oven to 500ยฐF and make sure you have steaming container handy – a cast iron pan or a loaf pan with water-soaked towels.

Divide and Shape. Slide the dough out of the bowl onto a well-floured surface. As with the lamination step, gently pull the dough into a square with roughly even thickness, then cut it into two equal halves. Gently tug each half into long rectangles (forming the slippers). Then holding a rectangle at each end, bring your hands together to scoop the rectangle and place it onto a well-floured couche or towel. Once it’s on the couche, gently tug it back into shape. Once both loaves are on the couche or towel, gently dimple the tops of each piece to promote even rising.

Final Fermentation. This can take anywhere from 30 minutes to 2 hours. What you want to watch for is that the loaves are nice and puffy with obvious bubble formation on the skin. Exercise some patience here because with natural yeast, things happen A LOT slower than with commercial yeast, and if you bake the dough too early, you will not get very good bubble formation!

Bake. Get some hot water into your steaming container to get the steam going in your oven about 10-15 minutes before baking.

You’ll really need a flip board for this so as not to degas the loaves. If you don’t have one, you’ll have to basically do the same motion as putting the loaves onto the couche to transfer the loaves to either a baking sheet covered lightly with cornmeal (if you don’t have a baking stone) or flipped onto a transfer board sprinkled with cornmeal or semolina.

Quickly place the loaves into your oven and immediately turn the heat down to 475ยฐF. About five minutes into the bake, check to make sure there’s still water in your steaming container. If not, replenish it (see notes). Bake with steam for 12 minutes then remove your steaming container(s) (I use multiple to ensure steam is produced faster than it can be vented) and reduce your oven temp to 425ยฐF. At this point, the loaves will have started to take on color. Bake for another 12-15 minutes or until the crust is a deep golden brown. You can let these cool if you want, but there’s nothing like slathering a hot slice of ciabatta with butter and honey!

Notes

  1. Some bakers I’ve encountered talk about not being able to keep steam in their ovens. I can’t either. Like almost all domestic ovens, my oven is designed to vent moisture. But if you produce more steam than the rate that the oven can vent it (I use multiple containers), you’ll be able to maintain a steamy environment. Furthermore, when you bake with steam, you need to check to see if your water has burned off during the time you need to be steaming! I always check my steaming containers 5 minutes into each bake to make sure they’ve got plenty of water to do the job.
  2. Once you add the olive oil, the dough will really feel liquidy. Don’t worry and please don’t add flour. Olive oil is like a gluten lube. It increases a dough’s extensibility immensely and in addition to adding great flavor, contributes to the production of large bubbles.
  3. Speaking of olive oil, do yourself a favor and use nothing but real extra virgin olive oil, not the cheap grocery store stuff.

Baking By Feel The Old School Way – No Recipe!

I woke up early this morning with a question in my head: Am I being a bit too academic with my bread-making? Like many bakers, I live by my formulas. They ensure that my loaves are consistent, no matter what I bake. But it occurred to me that bakers long before me had been baking by feel for centuries. They’ve developed a certain instinct about how their dough should look and feel.

Then I remembered watching four-part series on Netflix by Michael Pollan called Cooked. In the bread episode, there was a woman who made her bread in a wide bowl, just adding her ingredients in a seemingly free-form manner. It was fascinating watching her work! Then I harkened back to a video I saw of an Amish farmer making bread. No measurements, just going by the consistency of his dough. Again, fascinating. Then finally, at the world-famous Poillane Bakery in Paris, the bakers don’t use any measuring devices. They study the process for a year and a half!

That got me thinking: Have I developed those kinds of chops? After all, I’ve been baking bread for over 40 years. And especially in the last year, I feel I’ve developed certain instincts of how my dough should look, feel, and behave. So I decided to challenge myself today and go completely native, that is, use absolutely no measuring devices of any kind to assemble my dough.

The Starter

I had tailings leftover from my bake yesterday, so I fed my starter this morning with some AP flour, eyeballing the flour and water to relatively equivalent amounts.

I’m going to do something a bit different once it’s ready to be used and that is to mix it with a large quantity of water, then gradually add it to some flour until I get a consistency that’s similar to 65% to 70% hydration dough. This is consistent with what I do already by dissolving the starter in the water (sans a reserved amount for bassinage), then adding that to the flour.

I’ll let that mixture autolyse for a half-hour or so, then I’ll add the rest of the water and the salt, which I will also eyeball. Truth be told, I eyeballed what I think is 20 grams of salt based on the little crucible that I normally use for weighing my salt.

I am going to do a bit more of a bassinage. Normally, it’s about 50 ml of water. I think I may reserve more. I’ll play that by ear. Once I have the mix to the consistency I want, then I’ll do the standard 3-hour bulk fermentation with folds every 30 minutes or until I get about 25%-30% expansion.

I’m a little torn right now about the dividing and shaping. I’m a little anal about things being equal, so I’m leaning towards dividing my dough using a scale. But we’ll see when I get there… That said, I just might not do that to see if I have the chops to create consistently-sized loaves without a scale. We’ll see…

As far as shaping is concerned, I will do my best to not use any bannetons. Everything will be hand-shaped. This means I will have to rely entirely on my dough development and shaping skills to produce loaves that will literally stand up. And as I write this, I’m actually pretty excited. In the back of my mind, I’m confident that I’ll be able to pull it off with good results. But as with anything, you never know until you see the finished product.

The Process

The first step in the process was to completely liquify the starter. This liquid would then be added directly to the flour as shown below.

Using a Danish dough whisk made quick work of bringing the liquid and flour together.

Once I had everything mixed, I dialed in the consistency of the dough by mixing by hand, adding a little extra flour and liquid as I didn’t feel I had enough dough. Mixing by hand at this point was important because it allowed me to really feel the dough.

Once I dialied in the dough’s consistency, I transferred it to my bulking container to autolyse for 30-45 minutes. After that’s done, I’ll add the salt and a little more liquid to get to the approximate hydration (feel) that I want. There’s whole grain Kamut in this flour, so I’ll probably go a little wetter with the final dough.

I will admit that I’ll be leaning a lot on what I learned in Tartine Nยฐ3 in developing dough with whole grain flour. In that book, Chad Robertson employs his basic country loaf process, but has some valuable handling tips (read: being freakin’ gentle with the dough) accompanied by a fairly long final fermentation that has made a HUGE difference in how my whole-grain loaves come out.

After five sets of stretch and folds, the dough was super extensible, so I decided not to proceed with the sixth fold and let fermentation proceed untouched for another hour or so. Since I have a lot of high-extraction and whole grain flour in the dough, I need to be absolutely careful to not degas the dough and ruin all the work it has done the last two and a half hours.

I’ve mentioned in the past that I try not to be too parochial with recipes and techniques. That’s important because dough is affected by so many different factors. For instance with this particular batch of dough, about a third of the flour is really strong high-protein flour (17%+). I usually use it in conjunction with whole grain flour to help compensate for the bran that tends to cut the gluten.

But I have to say that at this point, the dough is feeling absolutely luxurious and is beginning to get nicely aerated. I should be shaping in the next couple of hours.

The Next Day…

Yeah… I was going to freestyle the loaves, but I ran out of time as I had plans for the evening. So I decided to shape up a couple of batards, put them in baskets and let them do their final ferment in my dough retarder. And yes, I did scale them out, though I got VERY close eyeballing them when I originally divided the dough and only fell about 20 grams short on one piece. Next time, I’ll probably just eyeball it…

But it’s probably best that I put the dough in baskets. When I was shaping the loaves, They felt like they were 90%+ hydration. Of course, I don’t know

The loaves are looking great in the oven right now! I was expecting the loaf on the left to be a little flatter than the one on the right as it came out of its banneton a little cockeyed. Oh well… But I’m loving the oven spring! With the predominance of whole-grain and high-extraction flour in my flour blend, I wasn’t too concerned about vertical lift. However, I was VERY concerned about overall spring and oven expansion. The wide fissure on each loaf indicates that the loaves expanded quite a bit and that pleases me to no end!

Notice how high up my baking stone is in my oven. I think I can go one more notch higher before my loaves touch the top. The reason I’ve got them up that high is that I used to have it down a few notches and I wasn’t getting enough steam on my loaves. With my stone higher up, all the steam created by my soaked towels and the water in the broiler pan at the bottom go right to the top of my oven. It’s kind of difficult to see in the picture, but the skin on each loaf at this point is quite damp. Since I’ve done that, my oven spring has been absolutely stellar!

I just pulled these out of the oven. I am VERY pleased with the results! Admittedly, it was a little nerveracking at first because I’ve been so used to being fairly exact with my measurements. But having gone through it and trusting in my dough development skills, I’m probably going to do this a bit more often.

That said, what I will definitely do is have predetermined flour blends that I normally use – I’ve been meaning to do this for a while anyway. This will make it easy to assemble my dough and take a little guesswork out of my different doughs’ performances so I should be able to achieve a fair amount of consistency.

Finally got a crumb shot of my loaves! Wow! I wasn’t expecting them to have such an open crumb because of all the bran in my dough. But hey! Who’s arguing? ๐Ÿ™‚ I kind of felt as if I’d get a good crumb, because of the great oven spring, but did not expect it to be this good. In any case, the bread was a hit at the dinner party I attended this evening. It was a going-away-to-college party for one of my daughter’s friends so there were lots of teenagers there. They devoured the bread! I was quite pleased to see that!

I Like Big Bakes…

I’ll let you complete it.. ๐Ÿ™‚

Yesterday I baked 8 dozen butter buns for another luncheon today at the Opportunity Center in Palo Alto, CA. I normally provide them with a few Poillane-style miches, but my wife, who now runs the outreach program for our church, came up with a new luncheon menu: BURGERS!

I didn’t consider that a bad thing at all, but it did mean scaling the recipe up to a size that I previously hadn’t baked. We’re talking over 21 pounds of dough! The most I had baked for the Center was just over half that amount, as I’d make four 3 1/2 pound miches. I’d easily be able to cut those up into 100-120 slices.

But this bake? This was different. Not only did I have to stage the actual baking, I had to stage the entire production as my mixer could only handle the dough for 24 buns. So I had to do a bit of planning.

The way I figured it, since I could bake on baking sheets, I could bake 48 buns at a time using convection to ensure an even distribution of heat. That wouldn’t be a problem. The challenge was going to be making the dough batches. With the amount of yeast the recipe calls for, as soon as I transferred a batch to one of my bulking containers (I used two, big 8-liter rectangular bulking tubs), the batch would start rising quickly, so time was of the essence.

The idea was to do two separate big batches with each bulking container holding the dough for 48 buns apiece. To deal with having to make two batches in a row, I kept the temperature of the water of the first batch below 70ยบF. Working the dough in my mixer would raise the temp a couple of degrees so the dough would start at about 72ยบF. Then with the second batch, I’d make the water temp around 86-89ยบF. Then when I combined the two batches, the final temp would come out near 80ยบF, which is the optimal temperature for this dough. OMG! It worked!

This was a very active dough, so I didn’t immediately start making the second big batch until the first batch of 48 buns was in the oven. I probably should’ve waited a little longer as the buns weren’t cooled down long enough for me to clear the counters. So I had to pop that batch into my retarder fridge. That slowed things down a tad, but that dough still rose a ton and was pushing the lid off the container by the time I was ready to shape. The next time I bake this amount I’ll take that into account. But I think what I’ll do instead is simply do the bulk fermentatino of the second batch at a lower temperature.

Details, details. But I love it! With baking, there’s so much that I have to consider all the time; not just in the present, but also the corrections I have to make for future bakes.

Butter Burger Buns!

Yesterday before she left for work, my wife prepared one of the family’s favorite dishes: The meat for Turkey-Mushroom and Swiss Burgers. As she was walking out the door, she asked if I could make burger buns – specifically buns I’ve made a few times that are light, airy, chewy, and packed with yeasty goodness. With the butter and sugar in them, they’re very similar to brioche, but not as sweet and not as buttery – but they’re close, which is why I call them butter buns.

But I have to be honest: This is NOT my original recipe, though I’ve refined it over the last year. This is a riff on King Arthur’s “Beautiful Burger Buns” recipe. And these burger buns really are beautiful. But not only that, they’re super easy to make!

When I first made these buns, I was surprised to see that there was no milk or powdered milk used in the recipe. I was also surprised at how low the hydration was (46-48%). But the egg and butter make up for the lack of hydration. Plus, the butter combined with the egg gives the crumb a slightly yellowish hue.

And though there’s sugar in the formula, these buns are not sweet overly sweet. The sweetness is much more subtle considering the amount of sugar used.

I’ve made these buns several times and to be honest, I recommend using a mixer, especially if you’re pressed for time. I made the buns entirely by hand yesterday and hand-kneaded the dough. But I had a bit of time, and hadn’t kneaded by hand for a long time (gotta keep my chops up). In any case, let’s get into the formula:

Overall Formula

Baker’s %Final Dough
AP Flour (pref. unbleached, unbromated)100%473
Water (lukewarm)46%-50%207-225
Egg (1 lg. egg – room temp)8%36
Sugar12%57
Butter (room temp)7%33
Salt2%9
Yeast3%14
Totals179%808
Optimal Dough Temp80ยบF
This will yield 8 100g buns and provides 1% of loss during processing. Note that this is a warm bulk fermentation!

Dough Development

Note that the hydration is 46%-50%. On cooler days, I recommend using the lower number. On warm days, use the higher number. That said, I always start with the lower number, then as I’m mixing will add a bit of water to get to that smooth consistency. Also, make sure your water is nice and warm! It helps incorporate the butter much easier.

Preparation. Before you start mixing the dough, mix the water, sugar, and yeast together in a mixing bowl to dissolve the sugar and activate the yeast; yes, even if you’re using instant yeast. Beat the egg so the yolk and white are well-combined. Note that I don’t bother measuring out the weight of the egg if I’m making a single batch and just drop a large egg into the mix. But if I scale up, I will beat a few eggs together and weigh according to the formula.

Mixing. Combine the flour, butter, and salt in a mixing bowl. Add the egg and water mixture and mix until all the ingredients come together there are no dry ingredients present. If you’re using a mixer, combine the ingredients at low speed, then once mixed go to the second speed to knead the dough for 2-3 minutes (dough should be smooth and pulling off the walls of the bowl). If mixing by hand, turn the dough out onto your board and knead until the dough is smooth (about 8-10 minutes).

Bulk Fermenation: 1-2 hours @ 80ยบF or until the dough has almost doubled. In warm weather, this will happen FAST! With this amount of yeast, bulk fermentation will happen pretty quickly so you need to keep an eye on it.

Divide and Shape. Turn the dough out onto your board, then scale out 100g pieces. Roll the pieces into tight balls (you can do two at a time), then let them bench rest for 10 minutes. Place each ball on a baking sheet lined with parchment paper and press them out into 3″ disks. Gently dimple the tops as you would a ciabatta (believe it or not, this promotes even rising). If you’re using a standard-size baking sheet, you might want to stagger the pieces so they fit better. Don’t worry if they touch when you press them out. They’ll expand even further during final fermentation and baking.

Final Fermentation. Allow the shaped disks to rise for up to another hour or until they’ve clearly expanded and are puffy. On warm days, my dough’s ready in about 30 minutes. In any case, check them after about 30 minutes. Preheat your oven to 375ยฐF.

Baking. Right before you bake, lightly brush the tops of the buns with melted butter. Bake them for 15-18 minutes until the tops are a light, gorgeous, golden-brown. Remove from the oven, then brush them again with butter. Cool for at least an hour before cutting.

Some Alternatives

I love this formula because you can use it for a couple of different kinds of bread besides burger buns!

Dinner Rolls. Instead of flattening out the rolls, place them in a round or a 13X9 pan to make dinner rolls.

Hawaiian Rolls. Half the sugar, up the butter to 10%, and replace 70%-75% of the water with pineapple juice and you’ll get a VERY close approximation to Hawaiian bread! Load the rolls into a pan as with the dinner rolls! You could also replace the remaining water with milk for an even fluffier texture!

Know Your Flour!!! Dammit!

I made the loaf above a few days ago. It tastes great. It has a great texture. It is flat! Flat! FLAT!!! F$%k!!! The worst of it is that I knew it would turn out like this because it was WAY too hydrated for the protein content of the flour I used. Well… serves me right for following a recipe without compensating for the ingredients I had on hand.

That loaf is Chad Robertson’s 60% Kamut loaf from his Tartine No. 3 book, which focuses entirely on baking bread with whole grain flour. In his recipe he mentioned, “Due to the high protein in Kaumut flour, this dough can take a lot of water.” Stupid me, I took that at face value and made the bread straight from the recipe before checking on the actual protein content of the Kamut flour I have.

My Kamut flour is only 11.7% protein, the same protein content as AP flour. And I upped my hydration to 92% based on his notes in the book that say he usually takes the hydration up past 90%.

STUPID! STUPID! STUPID!

I’m actually laughing as I write this because it’s SUCH a rookie move. And I admit that I probably let my excitement over Chad Robertson doing a recipe with one of my favorite flours get the better of me. And in my zeal, I pushed through the process and didn’t spend enough time studying. Oh well, lesson learned.

This time around, there are a few things I’m going to do to make this a successful bake:

  • I will use vital wheat gluten to up the protein content of my flour to provide more mechanical strength. I did some research and I saw Kamut flour ranging in protein content from 15% to 17%.
  • One thing I missed in Chad Robertson’s instructions was that he does a fermented autolyse in that he performs his autolyse with the starter incorporated into the flour and water. I will do that this time around. That will really get the yeast in my starter going!
  • I will also stick with his basic 85% hydration to start out with. If the dough is still a little stiff at this level, I will do a bassinage in one of my folding sessions to give time for protein to build up first.

As much as it is frustrating, I love the learning process. I may swear a lot in the process, but damn! A good finished product trumps any failures!

Happy Baking!

Vacation with Your Sourdough Starter? F$%K THAT! :)

I was on a home baker’s forum and saw a post where some dude’s wife took pictures of him proudly displaying his jar of sourdough starter that he just pulled out of his suitcase. The caption read something like, “My hubby took his starter with him on vacation!” When I saw that picture and read the caption, I chuckled, then thought to myself, I thought I was obsessive… But this takes it to a whole different level! Several people chimed in on the discussion thread and said they had done the same. That kind of amazed me.

Then I asked myself, “Why in the world would someone do that?” The only thing I could come up with is that home sourdough enthusiasts seem to have this notion that they have to feed their sourdough every day – some even twice a day – thinking that their starter will die if they don’t feed it.

Though I do my best to be nice, there’s no other way to put this: Your starter won’t die if you don’t feed it. And yeast is extremely hard to kill! In other words, go on your damn vacation and don’t let your starter dictate your schedule! ๐Ÿ™‚

I studied Biology in college with an emphasis on Microbiology and Virology. Though that was decades ago, one of the things I learned about yeasts is that they’re extremely hard to kill. As opposed to dying, when they don’t have a food source, they enter into a sort of suspended animation and go dormant. They can be in this state for thousands of years and be revived, amazingly enough (click on that link – it’s pretty fascinating).

So where does this daily feeding thing come from? Probably from professional bakers or home enthusiasts who bake sourdough every single day. They have to be on a schedule because they need their starter daily. But for those who don’t make sourdough every day, there’s just no need to feed the starter until it’s needed. In the meantime, it can sit in the fridge.

And why go through the hassle of discarding all that flour? It’s nonsense. From a purely practical standpoint, how many crackers and pancakes can you eat? Sheesh!

Look, I bake every day, but I don’t feed my starter daily because I don’t make sourdough every day. So when I’m not making sourdough, my starter is in the fridge. When I know I’m going to bake sourdough bread, I begin feeding it the day before – no discard, by the way, and I’ll get into my method below – or early that day if I make my dough in the afternoon.

For me, I use a tailings method with all my starters (I currently have 3 in my fridge right now). In each Kilner container, I probably have 100 grams of starter. When I’m going to use one, I remove it from the fridge, add 100 grams each of warm water and flour for the first feeding, then when it doubles, I do another feeding. The amount of flour and water I use varies based on how much starter I’ll need. I’ll actually make more than what I need so I will have extra once I add the starter to my dough. That extra – the tailings – goes back into the fridge.

This morning, I revived some tailings that are well over a month old as I have been traveling this past month and have only managed to bake yeasted bread while I was home. As of this writing, the levain I’m building is in the midst of its second feeding and it’s highly active. I’ll be ready to build my dough in another hour or so – that’s literally four hours since I removed it from the fridge! The point is that I let it sit for a long time and it still came back.

That said, yes, a starter can indeed slow down. But kill off the yeast? It’s highly unlikely unless the starter was exposed to some really extreme conditions. But in a cold environment like a fridge, all the microbes slow down, so competition in the environment will also slow (read: You can let it sit for quite a while).

But… if you want to take your starter on vacation, no one’s stopping you. But if it’s because you feel you have to feed every day, you just don’t need to do it. Pop your starter in the fridge and go enjoy yourself. Don’t let your starter dictate what and when you can do things.
