Autolyse: Take some flour and water and put them in a bowl. Stir them together until they are mixed, but don’t worry if it’s not perfect. Let the mixture sit for 45 mins. This helps the flour absorb the water better, which will make the texture nicer.
Mix the Dough: Add the active starter, sugar, and salt to the autolysed dough. Mix well to combine.
Bulk Fermentation: Over the next 3-6 hours, perform stretch and folds every 30-60 minutes. This develops strength in the dough and encourages even fermentation.
Add the Chocolate Chips: Gently fold in the chocolate chips during the last few sets of stretch and folds. Be careful not to overmix, as this can degas the dough.
Make the Dough: Carefully form the dough into a round or oval shape.
Proof: Place the dough in a well-floured proofing basket. Cover and refrigerate for 12-24 hours for best flavor.
Bake: First, heat your Dutch oven in an oven set to 450°F (232°C) for at least 30 minutes. After it's hot, carefully take it out and use a sharp knife to make cuts on the surface of the bread. Place the bread inside the Dutch oven, cover it, and bake it for 20 minutes. Then, take off the lid and bake it for another 25-30 minutes, until the crust is a deep golden brown color.
Cool: Let the bread cool completely on a wire rack before slicing and enjoying.
