This is so simple.
1 part dried beans (black, pinto, kidney, etc.)
3 parts water
Put in your crockpot and heat on low overnight. Approximately 10 hours. Done. It’s that simple. Once you’ve got these beans cooked, you can use them in any recipe calling for beans!
You never need to buy canned beans again. This one thing alone can save you a LOT of money over the course of a year. I have often found very large bags of dried beans and legumes in the ethnic section of the grocery store for a lot cheaper per unit than the regular size bags in the bean section.
I like to make a massive batch and then freeze them in smaller portions in ziplock bags.
