The most delicious and tender pulled pork carnitas you’ve ever tasted!
Add the rest of the stock and all the meat (and bone if you have one) then pressure cook the carnitas meat for 20 minutes on high. Allow the pressure to release naturally for 15 minutes, then manually release any remaining pressure. (Note that the Instant Pot will take between 15-18 minutes to come to pressure depending on how much meat you’re cooking.)
Strain the fat, onions, and garlic out of the liquid, pour a bit over the pulled pork, and toss. (If you want a thicker sauce, after it's strained, put it back in the Instant Pot and saute it for 5-10 minutes. You can even add a cornstarch/water slurry to thicken it up even quicker.) If you don't use all the cooking liquid be sure to save the rest to use to reheat the meat or in case you want to use it for soup later.
If desired, broil the meat for 2-3 minutes on a baking sheet until the edges are crispy.
