It was a hit with my parents. The pork was tender and juicy, just like it should be. I think I had too much water in the pot. Surprisingly, the pork had a pop-out indicator (whatever it's called). I took that out but I guess I could've left that in to make sure the meat was cooked. Not sure how it'd work in a pressure cooker environment.
The recipe calls for 3 cups of water. Seems a bit much to me but having to much is better than running out of water in a pressure cooker.
It was a simple recipe, nothing fancy. I browned the meat in a little bit of olive oil and seasoned it while it was browning. Took out the meat and put in the trivet. Added water and chopped onions, meat on top. Start the pressure for 30 minutes. Drop the pressure (fast), add potatoes, pressure again for 15 minutes. Drop on it's own accord.
