Save money using dry black beans instead of cans
Rinse the beans, and then dump them into the crock pot. Add the 12 cups of water and any optional seasonings, then cover and cook on high for 3-5 hours. If you decide to use salt, I recommend adding it during the last hour. I never add salt, and I think it tastes fantastic….but to each his own! My beans usually take a bit over 4 hours to fully cook. You can tell they are done by removing one bean and blowing on it. If the skin easily peels back from the bean, they are done.
