What is final proofing?
Final proofing is the last stage of fermentation, occurring after the dough has been divided and shaped. During this stage, the dough continues to ferment, producing carbon dioxide that expands the air pockets created during bulk fermentation. The dough also relaxes and becomes lighter and more aerated, preparing it for baking.
Place the shaped dough in a container, such as a proofing basket (banneton), bread pan (stainless or nonstick) or pullman loaf, and cover it to prevent the surface from drying out. Place the dough seam-side up in a proofing basket, or seam-side down when using a container that will also be used for baking.
The dough can be proofed at room temperature or refrigerated for a slower fermentation. A cold proof can be particularly useful for sourdough because it allows fermentation to continue gradually while also making the dough easier to score and handle. (Refer to my Scoring Dough page for a guide.)
The length of the final proof depends on factors such as dough temperature, starter activity, hydration, and the amount of fermentation that occurred during bulk fermentation. Rather than relying solely on a specific amount of time, look for signs that the dough is properly proofed. It should appear noticeably expanded, feel lighter and aerated, and respond to a gentle press with a slow, springy return.
Underproofed dough will typically feel dense and spring back quickly when pressed, while overproofed dough may feel very soft and fragile and fail to spring back. Learning to recognize these signs is more reliable than following a set proofing time.
