Step 3: Bulk Fermentation Stage
Rest the dough for a total of 4 hours, performing a stretch and fold routine after every hour. Stretch and fold: Wet your hands so the dough doesn’t stick. Stretch or pull up gently on one side of the dough without tearing it. Then fold it over itself, turn the bowl a quarter turn and repeat the stretch on the other 3 sides until all 4 sides are stretched. Cover and repeat each hour for 4 total stretches. It will be tougher to stretch towards the end as the dough develops.
Step 4: Shape the Loaf
After the 4th stretch and fold, lightly flour your work surface to shape the dough. Flour your hands, turn the dough out onto the surface, and gently stretch and shape the sourdough bread for your cooking pot.
- Shape a Round Loaf: stretch the dough from the top down onto the center. Turn a quarter turn and repeat until all the sides are folded in.
- Shape an Oval Loaf: Fold the sides of the dough alternating left and right from top to bottom. Then tightly roll the dough from the top to the bottom.
Step 5: Bench Rest
Let the dough rest for 20 minutes. First, turn the dough seam-side down. Then cover with a towel. After 20 minutes, if it seems to have loosened up too much, gently re-shape it using the same process as above.
Step 6: Tighten the Loaf
Flour your hands and cup the outsides of the dough. Then tuck the sides of the dough underneath. Slide the dough down the counter in a circular motion about 6 inches, using its slight stickiness to tighten the ball/oval. Don’t over-flour your surface and try not to tear the dough.
Pro Tip:
A banneton is a bread basket made to hold dough as it ferments. It should be shaped to match your pot (oval for oval baking dish, round for round baking dish). Before your first use, season the basket or liner by lightly spraying it with water, dust generously with flour (preferaby rice flour for a nicer crust and less sticking), let it fully dry then scrape out any excess with a spatula. Always let it fully dry after use and scrape out excess flour before storage.
Step 7: Cold Fermentation/Proofing
Flour the banneton proofing basket, or tea-towel-lined bowl generously. Place the dough inside seam-side up and cover with a towel. Refrigerate overnight or for at least 8 hours. It can stay refrigerated for up to 48 hours until you’re ready to bake the sourdough bread. It will rise slightly but won’t double.
Step 8: Preheat Oven
Preheat the oven to 500 degrees. This may take 30 minutes or up to 60 minutes for some ovens. If using a combo cooker with low sides, cut a piece of parchment to cover the bottom. If using a Dutch Oven with higher sides, lay a piece of parchment on the counter. Put the Dutch oven/combo cooker into your oven to heat (without the parchment) at least 30 minutes before baking. Set your pizza stone on the bottom rack, if using (a pizza stone helps to keep the bottom of the bread from getting too dark).
