What does proofing mean in baking?

Proofing, in one line

Proofing is the final rise of shaped dough, when yeast makes gas that fills the dough and makes it puff up before baking.

Why it works

Yeast eats sugars in flour and releases carbon dioxide and alcohol. The gluten network traps the gas, so the dough puffs. Warm temperatures speed it up and cold temperatures slow it down while building more flavor. Dough is ready when it has grown by about half to double and springs back slowly when poked.

How to do it

Common mistakes

  • Proofing in a cold kitchen without extra time, which gives dense bread.
  • Overproofing, which makes dough sag and bake flat.
  • Using water that is too hot, which kills the yeast.

Questions about proofing

How long does dough take to proof?

Usually 30 to 90 minutes in a warm spot. Cold proofing in the fridge takes 8 to 24 hours.

How do I know when dough is proofed?

Do the poke test: press a finger in, and if the dent springs back slowly and partially, it is ready.

What does proofing yeast mean?

It can also mean testing yeast in warm water with sugar to make sure it foams and is alive.
