Feed your starter and keep it somewhere cozy, like 75°F, to speed things up to about 6 hours. Cooler spots (65-68°F) might mean waiting 12 hours until bubbly and ready.

Use a big bowl to mix cocoa, sugar, salt, and flour. Add the sourdough and warm water. Stir until you don’t see any dry bits. Cover with a wet towel to let the dough rest and hydrate for 20 minutes.

Stretch the dough using wet hands and gently work in chocolate and cherries. Repeat this stretch-and-fold process 4 times, resting the dough for 20 minutes after each round.

Let the dough sit in a covered bowl and rise until it’s about twice as puffy, with tiny bubbles showing up. This could take 4 to 12 hours, depending on the temperature and how active the starter is.

Dust a banneton with rice flour and place the shaped dough in it, seam up. Pop it in the fridge overnight, anywhere from 12 to 16 hours for slower proofing.
06 -
Warm your Dutch oven to 450°F. Just before baking, add slashes to the dough and throw in two ice cubes to create steam. Cover and bake for 45 minutes, removing the lid to darken the crust for 5 more minutes at the end.

Set the finished bread on a cooling rack for at least 2 hours (up to 4 hours). Once it feels fully cool, slice and enjoy.
