Knock back dough to expel CO₂ after the first rise

After the first proof, “knock back” the dough by forcing out the built-up CO₂ gas before dividing/shaping.

Turn the risen dough out onto the bench and knock it back, which the presenter defines as forcing the built-up CO₂ out of the dough. Then re-form into a ball before portioning.

The short version

  • Knocking back = expelling built-up CO₂
  • Do it after the first rise before dividing

How to do it

  1. 1

    After the dough has doubled, turn it out onto the bench (unfloured, if it was proofed in an oiled bowl).

    It should slide out easily if the bowl/dough were oiled.

  2. 2

    Knock the dough back to force out the built-up CO₂ gas.

    Focus on expelling trapped gas before reshaping.

Why it works

Degassing redistributes yeast food and gas pockets, helping create a more even structure and making portioning/shaping easier.
