Soak the kidney beans overnight in plenty of water. Drain and pressure cook with 3 cups of water. After the beans are cooked, drain and reserve the water.
Making the refried beans
In a pan, put in the oil or butter and then add in the spices. Immediately, add the beans, sauté well and add a cup of the reserved cooking water.
Cook until all the water is evaporated. You can mash the beans a little. I like to leave the beans as they are but cooked until soft and mushy.
