Feed your sourdough starter 6 to 12 hours ahead of time so it’s bubbling and active. Warmer spots (around 75°F) can get it ready faster, while cooler temperatures (65-68°F) take longer.

Stir together the bread flour, white sugar, kosher salt, and cocoa powder in a big mixing bowl. Add in the sourdough starter and water, mixing until no dry patches of flour remain. Cover with a damp cloth and let the dough sit for 20 minutes to hydrate and loosen the gluten.
03 -
Using wet hands, stretch out the dough gently and fold in the chocolate chips and dried cherries bit by bit. Do a total of 4 stretches and folds, with a 20-minute rest between each round.
04 -
Cover the bowl and let the dough rise until it’s doubled in size with small bubbles visible. Depending on room temperature or your starter’s activity, this can take anywhere from 4 hours to as long as 12 hours.
05 -
Form the dough into a round loaf shape and place seam-side up in a banneton lightly dusted with rice flour. Put it in the fridge to cold-proof overnight for 12 to 16 hours.
06 -
Preheat your Dutch oven in a 450°F oven. Right before baking, slash the top of your dough and throw in two ice cubes for steaming. Bake with the lid on for 45 minutes. Want a darker crust? Leave it in for 5 more minutes with the lid off.

Set the baked loaf on a wire rack. Wait 2 to 4 hours to let it cool completely before slicing and enjoying.
