Pantry Refrigerator

Tips
  • Store in cool, dry area.
  • To test whether yeast is still potent enough to be effective: Add 1 teaspoon sugar to 1/4 cup warm water and stir in 1 envelope (or 2 1/4 teaspoons) of yeast; let stand 10 minutes — if the yeast foams up to the 1/2 cup mark, it will still be effective.
