Slap and fold kneading technique

Slap and Fold

This post might include affiliate links. Please see my policy.

This slap and fold technique is my go-to kneading technique for a wet dough. It takes a little practice to get the hang of it, and it gets a touch messy, but it's so effective at quickly strengthening a dough I almost always take this approach when mixing by hand.

I find this method most effective with a wetter dough, which for me is typically anywhere above 78% hydration. This hydration number is subjective, though, so you'll have to experiment to see when this technique is most useful. If the dough is overly stiff or too dry it's hard to stretch the dough sufficiently at each turn, in this case, I simply knead the dough in the bowl with a series of stretch and folds to bring it together after initial incorporation.

Be sure to read on to the end for a video of the slap and fold (French fold) process.

A tip to keep your hands and counter clean: wet your hands often with water, pausing periodically through the kneading process. Keeping them mostly nonstick will help avoid excessive dough-tear. Additionally, use a plastic scraper to occasionally stop and scrape the counter clean, reincorporating any stuck bits back into the mass (you can see me do this in the video below).

When to Slap and Fold

First, I don't usually slap and fold until after the autolyse step, if there is one. When mixing, I typically like to break it up into stages (and you'll often see this in my recipes) where I hold back salt1 and some of the mixing water until later in the mixing process. You can slap and fold for a few minutes right after incorporating just the flour, water, and sourdough, then add the salt and withheld water and do another slap and fold until strengthened to the desired amount. Or, you can slap and fold only once before the salt, or just once after everything is incorporated. This is up to you and your preference.

Dough Hydration

Excessive dough hydration can make the slap and fold process a little messier and sometimes even very difficult. If your dough is very highly hydrated, it can help to split mixing up into stages or even do a bassinage type mix, slowly adding water in through the mix to avoid a very sloppy dough in the beginning. For instance, withold some of the mixing water and begin slap and fold without the reserved water. Once the dough builds some strength, add in a little more to the dough in the mixing bowl and continue strengthening in a second slap and fold session on the counter.

Slap and fold: step by step

  1. Dump the incorporated dough to a clean work surface
  2. Using wet hands, grab one side of the dough to your left or right with both hands in a pincher type formation
  3. Pick up the dough (it'll hang long in front of you) and slap the long-hanging dough down onto the counter
  4. While still holding the dough, stretch it towards your body (the dough slapped to the counter should stick and anchor so the whole mass elongates)
  5. Quickly fold the dough nearest your body in the air over the anchored section on the counter (it will fold up into a tight package)
  6. Repeat (note that the dough rotates 90° each time you perform these actions to ensure the entire mass is strengthened eventually)

In the image above you can see the pincher-type hand grip and the slap and stretch mentioned in steps 2, 3, and 4 above.

The “fold” in slap and fold

In the image above you can see the quick fold over after the slap and stretch. This motion folds the dough back into a tight little package, which is then picked up again at the right side with the pincher grip, repeating the process.

Folded after slap and stretch

Continue each step in this process, over and over, until the dough is sufficiently strengthened for the target number of stretch and folds you intend to do during bulk fermentation. For example, I typically slap and fold until the dough smooths out, stops sticking to the counter as much as the beginning of the process, and generally starts to hold its shape on the counter without any excessively shaggy sections. This would mean I'd still need 1-3 sets of stretch and folds during bulk to finish strengthening the dough for my typical doughs.

You can see the dough is smooth in the image above, not nearly as shaggy as the images above, and holds itself well on the counter. At this point, I'll proceed with bulk fermentation.

Slap and Fold Duration

This is highly dependent on the dough (the flour itself and the hydration) you're working with and your effectiveness in the technique, but a good rule for me is somewhere around 3-6 minutes to yield a dough that usually requires 1-3 sets of stretch and folds during bulk to finish strengthening. Note that I'm quite vigorous during this process and really give the dough a strong stretch at each step, if you're more gentle you might require a longer duration.

Slap and Fold: Video

This video really illustrates how a wet dough can go from super shaggy and loose to nicely strengthened by the end. It's worth a minute to scroll back and forth through the video to see how this transformation takes place in just a few minutes of kneading.

What's next?

This kneading technique can be used with almost any of the bread recipes here at my site. Specifically, I like to use it with higher hydration doughs like My Best Sourdough Recipe and also works well with loaves with higher whole grain percentages.

Happy baking!

  1. I find adding salt too early makes mixing more difficult as it has a tightening effect on the dough. While adding salt early can help prevent some oxidization of the dough during mixing, I find with hand mixing—and it's gentle nature—this isn't really a cause for concern.
