I love the black bean refried beans you get in the foil packet at the Hispanic store, but I’ve never made them from scratch.
(Does cooking beans in your Instant Pot clog the vent? I’ve seen recipes for beans and grains I’d like to try in it, but have been worried about that.)
I got that recipe from the local Donna Auscena papuseria. I was very impressed with their beans and was always trying to figure out what gave them such a unique taste. When ordering, I would lean over the counter and try to see what spices were on their shelf, but I could never figure it out. Finally, I asked the cook, and she just went on and told me. The green pepper was the secret ingredient.
