FACT: How do I know if my yeast is OK

To proof the yeast and make sure it's active, add one packet (1 teaspoon) active dry yeast to 1/4 c. warm water (between 110 and 115 degrees F) and stir to dissolve. (The water should feel like a pleasantly warm shower, or about the temperature you'd use for a baby's bottle. If it feels uncomfortably hot, it will probably kill the yeast.) Add one teaspoon of sugar. Let the yeast sit for five minutes. If the yeast is foamy and smells like bread, it's active.
