I haven't seen or baked with cake yeast in years and years. Today I received a bread recipe that calls for 1 3/4 ounces or 1/3 cup cake yeast. I buy my active dry yeast by the pound and there's no store here that has cake yeast. Can someone tell me what the equivalent of active dry yeast would be? I suspect the measurement would be less than the cake yeast but I could be mistaken. Thanks.
