I’m planning to cook about 2 pounds of black beans in my Instant Pot and want to make sure I account for any potential bean chemistry issues. I’ve already soaked the beans for a few hours, and I know that cooking beans in a pressure cooker often requires less time compared to traditional methods. How much liquid should I use for the cooking?

I also intend to add some aromatics like onions, cilantro, bay leaves, and garlic, along with a flavorful stock. In my previous experiences, I’ve encountered problems when adding certain ingredients to beans, particularly acidic ones that can prevent them from softening. Will adding onions and garlic before pressure cooking pose any issues?

    When cooking black beans in an Instant Pot, there are indeed a few chemistry considerations to keep in mind to achieve the best results.

    1. Soaking the Beans: Soaking beans helps to reduce cooking time and may aid in digestibility. Since you’ve soaked your black beans for a few hours, you’re on the right track. Soaking reduces phytic acid and oligosaccharides, which can lead to gas.

    2. Liquid Ratio: For cooking soaked beans in an Instant Pot, you’ll want to aim for a liquid-to-bean ratio of about 2:1. For 2 lbs of soaked black beans, you should use approximately 4 cups of liquid. This includes the flavorful stock you’re planning to add.

    3. Adding Aromatics: Adding aromatics such as onions, garlic, and herbs before cooking is generally fine. They will add great flavor to your beans. However, you do want to be cautious with the timing of adding acidic ingredients (like tomatoes or vinegar) until after the beans have cooked, as acidity can prevent beans from softening. Since onions and garlic are not highly acidic, they shouldn’t pose a problem and can be added at the beginning.

    4. Pressure Cooking Time: Cooking soaked black beans in an Instant Pot usually takes about 8-10 minutes at high pressure. Make sure to let the pressure release naturally for about 10 minutes before doing a quick release to help ensure even cooking.

    5. Salt and Seasoning: It’s usually recommended to add salt after the beans are cooked to avoid toughening them during the cooking process. However, if your stock is already salted, adding it in your liquid as is should be fine.

    With these considerations in mind, you should be well on your way to delicious black beans in your Instant Pot! Enjoy your cooking!
