Typically, one envelope of dry yeast contains 2 1/4 teaspoons of yeast. This package is also equal to one 0.6-ounce cake of fresh yeast. One envelope of yeast is usually enough for a loaf of bread made with 4 cups of flour.
Dry yeast is usable for all yeast dough recipes, including both sweet and savory versions. It is appropriate for both traditional baking and bread machines. When yeast is added to dry ingredients, the liquid used in a recipe should be heated to between 120 and 130 degrees Fahrenheit. If yeast is dissolved in a liquid, the liquid should be between 110 and 115 degrees.
