I love using my crock pot, but I recently lost my lid. Panic!!! The crock pot is completely useless without the lid, and I really didn't want to go buy a new crock pot if it wasn't necessary. I tried using foil over the top, and it worked extremely well. My husband loved pinto beans, and it made one of the best pots of beans I have ever cooked! Hope this helps someone else!!
