I don’t see Beano listed there. :-)
Sounds yummy!
If gas is a problem for you when you eat beans, try this simple cure for your problem and Beano will not be needed.
Put the beans in a large pot and cover them with water. Bring them to a boil and take them off the heat. This breaks the capsules surrounding the beans and allows stachyose, verbascose and raffinose, the gas-causing sugars, to escape into the water. Stir a teaspoon or so of baking soda into the water (to make it more alkaline) and let the beans soak overnight. Very important. Drain the soaking water off the beans and rinse them several times. (If you eat the soaking liquid, you will cause unbelievable discomfort for yourself and those around you). Then proceed with your recipe to cook the beans.
I prefer coarsely mashing the black beans before cooking. Also, while the beans are still in the crock pot and just before serving adding a bit of sherry is an excellent touch.
