For best results, make sure your starter is very active and bubbly before mixing the dough, as enriched additions like butter, sugar, and chocolate can slightly slow fermentation; if your kitchen is cool, extend bulk fermentation until the dough looks puffy rather than relying strictly on time. Use good-quality chocolate chips or chopped chocolate with at least 50–60% cocoa so they hold shape without burning, and avoid adding them too early or they may smear into the dough. Chilling the dough before baking helps the loaf keep its structure and makes scoring easier, while baking in a preheated Dutch oven traps steam for a better rise and crust. If you prefer a less sweet loaf, reduce the chocolate by 20–30 g or omit the sugar, and if your dough feels too sticky, lightly wet your hands instead of adding extra flour to maintain a soft, open crumb.
