How to Test Yeast to see if it's still Good

Step 1

Stir in all the yeast for about 15 seconds until combined and then leave it alone for about 10 minutes. After even just a few minutes, you should start to see the top bubble and lightly bloom or foam.

Step 2

After 10 minutes, the yeast should've doubled or tripled in size and should be high up. It should also have a yeast aroma. Good news - your yeast is fresh!

Step 3

If your yeast does nothing and you added the right temperature of water, your yeast is dead. Toss it, and get some fresh yeast. Happy Baking!
