Testing Yeast Activity

Step 1

1: Add the sugar and warm water to a 1-cup liquid measuring cup. Stir until the sugar is dissolved.

Step 2

2: Sprinkle in 1 packet of yeast. (Stir it if you want to, but you don’t need to)

Step 3

3: In a few minutes the yeast will be activated and start to foam.

Step 4

4: After 10 minutes the foamy yeast should have a rounded top and reach the top of the cup or higher.

Step 5

5: If the yeast reaches the 1 cup mark it is active. If it did not, discard it.

Step 6

6: Use the activated yeast right away in a recipe. Make sure to deduct 1/2 cup of liquid from the recipe.
