Turn IP to saute, add oil and chop onion.
Add onion to the IP and begin to saute, when about 1/2 way to softening, add in seasonings. I prefer a spicier bean with more flavor, so I add a full teaspoon of both cumin and chili powder. Saute seasonings with onion for a minute or two longer, keep stirring so it wont burn!
Add in water and deglaze the bottom of the IP. Deglazing is just scraping off the cooked bits left after cooking. It makes for wonderful flavor! Add in your soaked beans.
Place the lid on, lock into place, make sure your lid is set to seal. Press manual and set for 10 minutes cooking time. Allow your beans to natural pressure release.
When done cooking, if you want your beans a little thicker, pour off a little of your liquid (but not much!). I have found if I use the 1.25 cups of water, I can blend without draining and they come out great! They do thicken upon standing, so don't worry if they are a little runny. DONT FORGET to add your teaspoon of salt when it's time to blend! Pour that in, blend until smooth.
Enjoy!
