I read the sprouting guide in Alissa's book very carefully but my garbanzo beans haven't sprouted. They just have little tails on them after 3 days. Has anyone had this happen before? Do you think I either (a) soaked too long or (b) the beans were no good to start with or (c) I'm an idiot? Haha! Anyone who picks "c" is going to get a noogie sandwich.
