For best flavor and structure, ensure your starter is very active before mixing, and err on the side of a slightly longer bulk ferment if your kitchen is cool so the dough feels airy and jiggly before shaping. If the dough seems too sticky, lightly wet your hands instead of adding extra flour, which can dry out the crumb. You can adjust sweetness by increasing or decreasing the sugar or honey and vary intensity by changing the cocoa or espresso amounts slightly, but keep total hydration similar. Dark chocolate chunks hold distinct pockets of melted chocolate, while chips stay more intact; either works, but fold them in gently to avoid tearing the gluten structure. Slicing only when the loaf is fully cool prevents a gummy interior and helps preserve the open, tender crumb that pairs especially well with butter, mascarpone, or a light dusting of powdered sugar.
