Chocolate Starter Bread Recipe

ripe, 100% hydration

I used the French T80, which is partially whole wheat, plus 1 tablespoon wheat gluten

good-quality, unsweetened, Dutch-process

crumbled, substitute 1/2 teaspoon active dry yeast, I use the SAF brand

filtered, at room temperature

good-quality, I used one with a 60% cacao content, chopped to chocolate chip size on average, you'll have smaller and larger pieces, that's fine -- use them all
