Proofing
The final rise of shaped yeast dough before baking, allowing gas bubbles to expand for a light texture.
Proofing time: 45 to 90 minutes at room temp • 12 to 24 hours for cold retarding in fridge
Proofing (also called proving or secondary fermentation) is the final rising period of shaped yeast dough before it is placed in the oven. During this stage, the yeast continues to ferment sugars, releasing carbon dioxide gas that collects in the gluten air pockets. The goal of proofing is to aerate the dough to its peak volume, ensuring a light, soft, and chewable crumb structure after baking. Proofing typically occurs in a warm, humid environment (around 75°F to 85°F / 24°C to 29°C) to accelerate yeast activity while keeping the dough surface moist to prevent a skin from forming, which would restrict the rise.
Determining when dough is perfectly proofed is a key baking skill. Under-proofed dough will rise too rapidly and tear in the oven (excessive oven spring), while over-proofed dough has exhausted its yeast food, causing the gluten structure to weaken and collapse under baking heat, resulting in a flat, dense bread.
Baking over-proofed dough. The yeast has consumed all its sugars, and the air pockets have grown too large, causing the loaf to deflate in the oven's heat.
In the UK and Australia, this is spelled Proving. In French pastry, it is known as 'apprêt'. Cold proofing in the refrigerator is called 'retarding'.
Required for shaped yeast breads, rolls, croissants, cinnamon rolls, and pizza crusts before baking.
