Whether you’re new to the game or a seasoned professional, working with slack, high-hydration doughs can be challenging. They resist kneading, they stick to our hands, they’d rather slump than rise. But don’t give up. Over many years, in bakeries and my home kitchen, I’ve found a few tips — from baker’s math to folding, fermentation, and proofing — that will help you achieve the best bread of your life.

(To see these tips in action, be sure to check out our video 5 Tips: Working With High-Hydration Dough.) 

Tip #1: Know your dough 

Before we can get you out of what probably feels like a sticky mess, we need to know where you are. In dough terms, that means quantifying ratios using baker's math, a.k.a. baker’s percentages. In basic terms, baker’s percentages will clarify exactly how wet your dough is. This is important, as dough hydration will set expectations for how you develop strength (either kneading or folding), shape, and even how you proof.

Let’s do a quick review of baker’s percentages using our Rustic Sourdough Bread

Rustic Sourdough Bread 
227g sourdough starter 
600g all-purpose flour 
340g water 
1 teaspoon yeast 
15g salt  

Total hydration is found by dividing total water by total flour. In this recipe, the flour value is 600g plus the amount in the starter (which is equal parts flour and water, so the flour is 113g), for a total of 713g flour. The water value is 340g plus the amount in the starter (113g), for a total of 453g water. So, the total hydration percentage in this dough is 453/713, or 63%.

While this isn’t all the information we need, it does help. A 63% hydration dough made with all-purpose flour may be easily kneaded, but if hydration is increased to 80% it will respond better to folds.

Tip #2: Guide the fermentation 

We all know that bread is a fermented food like wine, prosciutto, and sauerkraut, but did you know that in addition to flavor, fermentation also serves a functional role in breadmaking?

As yeasts consume available sugars during fermentation, they produce organic acids and alcohol as by-products. The acids reinforce the structure of dough, strengthening and improving elasticity (the rubber-band quality). Without a healthy starter, good dough temperature, and ambient conditions — all of which support dough activity — fermentation will slow.

If fermentation slows too much, dough strength will suffer. While that might work with firmer doughs, with our high-hydration tightrope act, doughs literally fall without good fermentation, unable to support all the water.

How do we guide fermentation?  

On my next business card, I’d like to have the word “Baker” replaced with “Fermentologist.” It sounds silly, but most of a dough’s life is spent fermenting, not baking. And who guides fermentation? We do.

Three keys to fermentation:  

  1. Healthy starter. Our starter should be active — doubling or even tripling in a period of eight hours with many tiny bubbles and a sweet, yogurt-like aroma. We have reams of information on starters: this article on sourdough starter troubleshooting is a great place to begin if your bubbling pet is misbehaving.  
  2. Temperature. Knowing that the yeasts and bacteria in our dough are temperature-affected, we need to manage our dough temperature during both mixing and fermentation. At the end of mixing, most doughs do well in the range of 75ºF to 80ºF. There are exceptions, but this happy range encourages doughs to rise well but not so quickly that they don’t have time to develop flavor. The second part of the temperature equation is for the period of bulk fermentation (the time between the end of mixing and when the dough is shaped). In our cool New England home, I find a cozy place for doughs to rise, often with a view of the wood stove. And on hot summer days, a bowl of dough may sit on the steps to our basement. Regardless of where you are, finding an ambient condition around 75ºF will keep most doughs happy.
  3. Time. I consider this the secret ingredient; it’s not found on any label, but without it, fermentation doesn’t exist. Fermentation takes time. From 1 hour to 24 hours or more, each dough has its proper course. Don’t skip it. In fact, adding time is rarely a problem.

Tip #3: Fold for strength 

You’ve mixed your dough. The mass is homogeneous, and ahhhhhhhhhh, here comes the part where you work the kinks out of your week. Drop the shoulders, plant your feet, sprinkle a little flour, and settle in for a 10-minute session of blissful kneading. But instead of your usual moment of Zen, high-hydration doughs might leave you up to the elbows with a sticky mess, more stressed-out than ever.

Thankfully, there’s a method to develop strength in these doughs that’s frequently easier than kneading: folding. Here are three types of folds that will effectively strengthen dough (the purpose of kneading!). Our High-Hydration Whole Wheat Sourdough Bread employs each of these folds.

The bowl fold 

This fold is used in the early stages of fermentation, before the dough has significant structure. As you pull the sides of the dough up and press them into the middle, working around the mass, the dough will slowly gain structure. 


The coil fold

This fold is used in the middle stages of fermentation as the dough become more elastic. Lift the dough from the center, allowing it to elongate and stretch, so that it coils around itself.


The lamination fold

This fold, similar to a letter fold, is used in the later stages of fermentation when the dough has developed enough elasticity to stretch thinly without tearing. Spreading the dough thinly on a wet work surface significantly increases strength and elasticity.


Tip #4: Be gentle while shaping 

As with kneading, shaping also improves with a new approach. Using a heavy hand to compress the dough, adding muscle to the mix, is best saved for shaping firmer doughs. Here, a gentler approach is better, applying only the pressure required to seal a seam. Too much pressure and the dough will compress and tear, sticking to everything.

Here are two common shapes: 



Tip #5: Cold fermentation: Chill before baking. 

Cold fermentation (chilling shaped loaves overnight before baking) is a game-changer. What goes into the banneton as a gassy, wobbly mass firms up overnight, improving flavor and creating a skin that takes the cut of my razor or lame more easily. Holding shaped loaves in the refrigerator also allows flexibility in terms of scheduling the bake. I decide when loaves go into the oven, working a bake around my day as opposed to working my day around a bake.

Now that we know our hydration, control fermentation, fold for strength, shape gently, and chill our loaves before baking, let’s take our new skills for a spin.

At 95% hydration, this High-Hydration Whole Wheat Sourdough Bread recipe is technically high hydration. Each loaf is almost equal parts water and flour. But using the tips above, I guarantee you'll find more joy than struggles. Happy baking!
