re: book - sure! do you still have the book, or did you hand it back to me? (i recall someone doing so, but that might have been dana, before you borrowed it.)

regarding interesting grains, i've got a decent number of odd grains in my kitchen, which you're welcome to poke at if you're interested in trying something without getting a whole box or bag. (i'm afraid the catalog of grains will have to wait until i get home, though.)
