Yeast Substitutions

Use these formulas to convert from one type of yeast to another.

Compressed (fresh) yeast x 0.5 = Active Dry Yeast
Compressed (fresh) yeast x 0.33 = Instant Yeast
Active Dry Yeast               x 2 = Compressed (fresh) yeast
Active Dry Yeast               x 0.75 = Instant Yeast
Instant Yeast                    x 3 = Compressed (fresh) yeast
Instant Yeast                    x 1.33 = Active Dry Yeast
