How to Proof Yeast



How to Proof Yeast

It's a real bummer when bread fails to rise because it means you've wasted both time and ingredients. Fortunately, you can avoid this mishap by proofing your yeast before you use it.

Difficulty: Easy

Time Required: 10 minutes

What You Need:

  • Yeast
  • Water
  • Sugar
  • A bowl

Here's How:

Combine the yeast, warm water and sugar called for in your recipe in a bowl. Let sit for 10 minutes.

Note: If your recipe doesn't call for sugar, add a small amount (1/8 tsp will do it), to give the yeast something to feed on.

If the mixture is bubbly after the 10 minutes is up, the yeast is good. Add the mixture to the rest of your ingredients, and continue with the recipe. If the mixture isn't bubbly, your yeast is no longer good. Dump out your mix, and start with fresh yeast.


  1. Store your yeast in the fridge, and it will stay fresh longer
  2. Be sure to check the expiration date before you buy yeast
