Proofing

Proofing is the final rise of shaped yeast dough before baking, during which yeast ferments sugars and produces carbon dioxide gas that expands the dough to its desired volume. This step is critical for achieving the right texture, crumb structure, and lightness in bread, rolls, croissants, and other yeast-leavened products. Proofing is also called proving or final fermentation.

Optimal proofing conditions are typically 27–35°C with 70–85% relative humidity, maintained in a proofing cabinet or controlled environment. Under-proofed dough results in dense, heavy bread with poor volume, while over-proofed dough collapses during baking and produces a coarse, uneven crumb. The right proofing time depends on dough formula, yeast activity, temperature, and desired product characteristics. Experienced bakers judge readiness by the “poke test” — gently pressing the dough and watching how quickly it springs back.
