Cooking Beans in a Pressure Cooker

Look over the beans for rocks or dirt, then wash and rinse them two times. I usually cook 4 cups beans and cover with 3-4 inches of water above beans. (You can soak twice as many beans as you want to cook and when soaked and drained, you freeze 1/2 of the soaked beans for another day.) Put in the pressure cooker and cover with lots of water and let soak for 8-12 hours. When ready to cook, drain the beans and put in fresh water in the pressure cooker about 2-3 inches over the beans and add a pat of butter so they don't foam. Seal pressure cooker and put rocker on top and turn on high; when it rocks, turn it down to medium and cook for 25 minutes. Turn off stove and let it stand until valve goes down.
