Bread-Bakers v113.n024.6

Hi, Stephen,

Yup, 2.5 is the right fresh yeast-to-instant yeast conversion. And 
it's by weight, not volume.

So buy yourself a scale that measures down to the tenth of a gram 
($40?) and you can do the conversion. FYI,

* By my measurements, 1 teaspoon instant yeast weighs about 3.1 grams
* As a typical starting point, most bread recipes need around 2 grams 
of fresh yeast for every 100 grams of flour

Happy baking!
