Cold ProofA night in the refrigerator. The dough keeps working while you don’t have to do anything.What HappensAfter shaping, the dough goes into the refrigerator, covered in its banneton, at 5°C or below. At this low temperature, fermentation slows down considerably, but it doesn’t stop.The flavour and structure of the bread continue to develop, only at a much slower pace than during bulk fermentation.Meanwhile, the gluten structure also becomes a little firmer, contributing to better oven spring and a finer structure in the finished bread.Why This Step Is Worth ItCold proofing gives you something few other steps offer: flexibility.You can prepare the dough in the evening and bake it the next morning, afternoon or evening — whenever it suits you.Have an appointment in the morning? Bake in the afternoon instead. Need to leave early? Get up and bake before you go.The timing of the cold proof itself is therefore relatively forgiving. A few hours earlier or later rarely makes a dramatic difference. The flavour may develop slightly differently, and the crumb may be a little denser or more open, but the bread is unlikely to fail simply because of this timing difference.How Long Can It Last?Allow at least a few hours, but usually aim for a full night — around 8–12 hours.Beyond 24 hours becomes less ideal. The dough may continue fermenting too far and begin to lose structure.Make sure the dough is well covered during the cold proof. Otherwise, the surface can dry out, resulting in a less attractive crust.Can You Skip It?Yes. You can bake without a cold proof, going directly from bulk fermentation and shaping to the oven.The bread can still turn out well, but you miss some of the additional flavour development and the convenience of flexible timing.For your first few loaves, think of the cold proof primarily as a quality step — valuable, but not the reason a loaf succeeds or fails.From Refrigerator to OvenWhen you’re ready to bake, there is no need to let the dough warm up first.It can go straight from the refrigerator into the preheated oven and baking vessel.That cold, firm dough is also easier to score than dough at room temperature.See Scoring and Baking for the next steps.Part of The Baking Process.Continue reading: Baking · Oven Spring · Scoring
