To Robin:
I use the rapid yeast from Sam's for any type of faster baking, and even to
make sponges to get a more developed flavor for slower breads.  I keep it in
an air-tight canister in my freezer.  I still use "slow" yeast for some
things.  I  buy my slow yeast from my local food co-op.  It's one-quarter
the price of the jars from the grocery store.  These two different sources
of yeast save a considerable amount of money.
