I recently pulled the cooker out and did ropa vieja- chuck roast seared on all sides, couple peppers, a chopped onion, some garlic, a can of tomatoes and a good shake each of paprika, cumin and oregano. 30 minutes on high and then I released pressure and shredded the beef. It was like it had been in the crockpot all day! Very tasty.
One of these nights I’m going to try carnitas - either CSRs or pork steaks (any of that darker meat from the shoulder) with stock, wine, OJ, garlic, herbs/spices. I hear if you shred it after pressure cooking and then put it under the broiler for just a couple minutes, you get that nice crispy thing that carnitas usually has.
I've done many a pan of carnitas this way, but I use beer, not wine, in mine. When done, rather than shred, I cube it into about 1" cubes, then toss the cubes on a foil-lined rimmed baking sheet with some bacon fat that has been melted, then into a preheated 400* oven - toss the cubes every 5 to 10 minutes til they get as crispy as you like. DANG good stuff!
