I'm looking for a very readable book about baking science -- why baking powder works, how flours are different from each other, the proportions of a pound cake, etc. Does anyone know if "Butter Sugar Flour Eggs" by Gale Gand would fit the bill? I had remembered a title something like that, although the cover is much more colorful than the one I was thinking of. Also, from the Amazon listing, that one seems more about recipes than the science (which is the opposite of what I want). Thanks!
