do you use the same amount of instant yeast as you would in a recipe that calls for ady, is there any conversion advice anyone can give. i know you do not have to proof instant

Tommy,

Very best advice to you is to consult Hamelman's Bread. There you will find a conversion chart. Alternately, look at pizzamaking.com where you''ll find similar conversions, or Rienhart's The Bread Bakers's Apprentice. No, they don't convert easily, but give these tables a shot. Across the board, IDY is a faster alterntive than ADY, but there are exceptions, as in biga recipes. Depend on what you're trying to do.

I was searching around for exactly this answer and found this thread... I found this conversion guide from 911 baking and thought I would paste it here in case anyone else was searching and found this old thread.

There have been numerous discussions about this. It is a great topic. Look at this table:

[Mitchamus]

yes but that table is just for ADY.

[BrianShaw]

The rule-of-thumb is 25% less IDY than ADY.

It's been my experience that yeast makers are in business to sell yeast. A whole packet of yeast in a loaf of bread? What for? Try more like half a teaspoon.

I agree. I think they think of it as "insurance" to cover the liklihood that someone will improperly store and then expect it to work. Many recipes seem to want to rush the rise time -- a convenience, but certainly not a flavor building approach.
