Add the remaining ingredients and stir to combine. Then right before you cook, add 2 more tablespoons of oil to the beans. The oil prevents the beans from foaming up and clogging the valve. Very important that you don't skip that step. Follow safety instructions that come with the pressure cooker. Lock lid, heat to medium/high until safety valve seals and locks. When the pressure valve begins to spin or release steam at high pressure, turn heat to medium/low and set your timer for 32 minutes. after about 20 minutes, I turned the heat up slightly to finish cooking. Gently remove from heat. Once lock and seals opens and releases, them remove the lid.
