Ohhhhh I hope I'm doing this right! Making pizza dough and it sure seems like alot of yeast to me but I'll give it a try.
Recipe calls for: 3 1/2 c flour, 2 T yeast, 2 T honey, 1 c warm water, 1/4 c olive oil and 1/2 tsp salt. It's mixing in the breadmaker now. Here's a conversion I found. Instead of using the full 2 oz cake, I cut a little off:
How Much Yeast Does An Envelope (or packet) of Yeast Contain? (USA)
1 envelope or packet of Active Dry Yeast, Instant Yeast, Rapid Rise Yeast, Fast Rising Yeast or Bread Machine Yeast weighs 1/4 ounce or 7 grams which equals 2 1/4 teaspoons (11 mL).
Yeast Substitution Guide:
One (0.6 ounce) cube of Fresh Compressed/Cake Yeast equals 1 envelope (or packet) of Active Dry Yeast, Instant Yeast, Rapid Rise Yeast, Fast Rising or Bread Machine Yeast, which equals 2 1/4 teaspoons or 7 grams (11 mL).
If a recipe calls for 1 envelope (or packet) of Active Dry Yeast, Instant Yeast, Rapid Rise Yeast, Fast Rising Yeast or Bread Machine Yeast, then you would use 0.6 ounce Fresh Compressed/Cake Yeast.
2 ounces of Fresh Compressed/Cake Yeast equals a strip of 3 envelopes or packets (21 grams total), or 6 3/4 teaspoons approximately of Active Dry Yeast or Instant Yeast.
Shelf life of Compressed/Cake Yeast
Compressed/Cake Yeast only has a shelf life of 4 to 6 weeks. It is highly perishable. The "sell by" date on the package is the "expiration date" also.
