Hi! I've been using some great recipes that call for garbanzo flour. Since it isn't available locally and garbanzos are, I've been trying my hand at making flour. Not much success

. I've tried a food processor and a blender, and both seem to take forever to grind. Plus, I wore out my food processor!
The local mill says they'll grind it if I dry them in the oven for a few hours.
I looked on line for a mill that can do it, but most specify not to grind things like beans with soft centers.
Ideas, anyone?
Thanks!
