If you remember to soak your beans the night before, I salute you. This recipe is for the rest of us. On their own these rice and beans are bland as all get out, but after cooking you can spruce them up by stirring in some olive oil and a few dashes of Tabasco, or some sesame oil and soy sauce, or some recaito, or whatever you like. I've used black beans instead of kidney beans, and once made this with azuki beans and brown glutinous rice, all with equal success. Using a small metal bowl covered with aluminum foil inside your pressure cooker is recommended to prevent the foam that is produced by the cooking rice and beans from blocking the vent tube, which could be very, very bad. If you're tempted to forgo this saftey precaution, I urge you to check your owner's manual for recommendations on cooking rice and beans. Me, I'm lazy, and like having the bowl with its foil cover ready for storing leftovers.
