I read this thread last week and then a friend had accidently sent me a photo of her soup in the pressure cooker. Sent my daughter to get a pressure cooker and made taco soup from scratch last night. I cooked the black beans and red beans an hour on stove and let them sit put them in the cooker with all the other ingredients and the soup is perfect. Thanks for talking about those beans and getting them cooked right. I have had issues before with them so bought canned. Now I will be able to do even healthier cooking in the pressure cooker.
