Rinse your beans to remove any dust or debris from the bag.
1 14 oz bag of dried black beans
In the Instant Pot inner cooking pot place your rinsed beans, onions, garlic, pepper and water. Cover with a dish towel and allow to soak overnight (about 12 hours)
1 14 oz bag of dried black beans, 1 medium yellow onion, 1 green bell pepper, 3 cloves of garlic, 9 cups water
Once the beans have soaked over night, add salt and bay leaves and place in the instant pot and cook for 45 minutes in the soup setting with regular pressure.
Open your instant pot once it's safe and make sure your water didn't dry out. Give the beans a gentle stir. You can add water in ½ cup increments (upto 1 ½ cups) if the beans are absorbing the water too quickly.
Add the cumin, vinegar and olive oil and allow the beans to simmer for another 15 minutes uncovered before serving. Add additional salt to taste.
