Trying to experiment with (and use up) leftover black-eyed peas, I put three chopped rashers of bacon, one small chopped onion, one cup of dried black-eyed peas into the pressure cooker. I put in 3.5 cups of water, 2 tsp salt, and 0.5 tsp of ground cayenne pepper. I took it to high heat for 24 min and then let it come down in pressure naturally.
They came out delicious, but next time I would (a) reduce water to 2.5 cups, and salt and cayenne proportionally, and (b) reduce cooking time by a few minutes.
