Proofing (activating) yeast
Beginner Baking and pastry
Proofing yeast is mixing yeast with warm water and a pinch of sugar to check it is alive before making dough.

How do you do it?
- Heat water to 105-115°F; it should feel warm, like a baby's bath, not hot.
- Stir in the yeast and a pinch of sugar.
- Wait 5-10 minutes: it should turn foamy and smell bready.
- No foam means the yeast is dead; start over with fresh yeast.
Why does it work?
Yeast is a living fungus that eats sugar and gives off gas, which raises bread. Warm water wakes it up; water above about 130°F starts killing it.
What are the common mistakes?
- Using water that is too hot — kills the yeast and the bread never rises.
- Adding salt straight onto the yeast — slows it down.
