Yes I know it is ironic that I bought refried beans for the Mission Style Burritos then made beans the same day.
These I cooked overnight in plain water just to have cooked beans in the freezer, yes, again freezer for sides or other components to dishes. This technique works for any beans except red kidney beans. Red kidney beans need to come to a full boil, which some slow cookers do, and some do not. So in the end I just don’t buy red kidney beans. My regular beans are pinto, black beans, and chickpeas/garbanzo beans – I love garbanzo! But for now, the pintos.
