Several delicious sounding recipes like the refrigerator sugar cookies
that have been posted have cream of tartar included in them.  I am
currently in Germany for 10 mo. and have not found the equivalent material
here.  I'm pretty sure that it is a salt of tartaric acid but I'm not sure
which one. In German, Weinsaeure is tartaric acid and Weinstein is
presumably cream of tartar (for those who know German, it is the stone
(stein) found in homemade wine). Does anyone know the proper formula for
it? Thanks.
