Proofing Yeast

  1. If unsure of the age of the yeast or concerned about whether it will activate, use this technique to “prove” the yeast.  Add yeast to warm water or milk amount specified in recipe being used.  The water or milk should be warm, but not greater than 100 degrees to prevent yeast being killed by heat.
  2. Sprinkle about 1/8 tsp of sugar across top of yeast, stir into water or milk, and let mixture sit a few minutes.
  3. If the yeast is still good, it will begin to slowly “bubble up” or form small “mushroom clouds” or white foam on top of mixture within 5-10 minutes.  If it does not, the yeast is inactive and you need to start over with a fresh packet.
  4. Now you can be sure the yeast will be effective before adding it to the other ingredients.
