I bought a $25 pressure cooker I found at the grocery store that has changed my life. It's a simple stove-top aluminum pressure cooker. I primarily use it to cook either black beans or pinto beans, with various meats included.

Last night I made the most incredible feijoada I've ever tasted in just under an hour. I didn't even soak the black beans prior, used fresh dried black beans. If I'm cooking pinto beans, I'll soak overnight, but the black beans come out perfect in 45 min in the pressure cooker.

My feijoada:

1 lb dried black beans, comes in a convenient 1 lb package
Garlic, I lost track, probably 6 to 10 cloves, I push the limits with garlic and have never found anything to have too much garlic.
1 yellow onion, diced
2 T olive oil
2 ham hocks
1 small pumpkin, cubed
Several sausages, sliced
1 pig's foot
1 T. cayenne pepper
1 T. cumin
3 cups chicken stalk, 4 cups water
Brown the ham hocks, sausages, pig's foot, onion, and garlic in the olive oil in the bottom of the pressure cooker. Add the rest of the ingredients and pressure cook for 45 min to 1 hr.
