Marinate pork shoulder in all of the remaining ingredients for 24-48 hours.
After marinating, place both the meat and its sauce into an instant pot on high pressure for 15 minutes.
Preheat oven to 450.
Let Instant Pot naturally release pressure for 12 minutes.
Remove pork from Instant Pot and place onto a baking sheet in oven. Bake for 4-5 minutes or until edges are lightly caramelized.
While pork is baking, simmer the remaining sauce from the Instant Pot until it is reduced. You may want to pour out some of the excess oil from the surface of the liquid to decrease cook time (and increase the health of this dish!).
Slice pork thinly and serve over rice, spooning the sauce on top.
