My husband started to home brew recently and there are tons! of spent grains leftover from the process. I've composted some, made dog biscuits out of some and now I'm trying to bake it into bread. Seems logical to me, as they are whole grains, to use them again. I've tried several recipes from brewing forums, all to a general gummy effect. Anyone tried using them, toasting them, done anything with these grains?
