Em forwarded an Email from someone he'd worked with that had absolutely the best array of crockpot recipes one could imagine. I traced it back to a sublink of a group that's (for the most) broken up now, but agreed to keep the cookbook online indefinitely.
I've added the link to the sidebar and will add it here, as well.
Check out the Crock Pottery section. AWESOME! What CAN'T be made in a crockpot?
