Shred the pork with two forks, or with the paddle attachment of your
stand mixer, then toss with additional cooking liquid (about 1 cup), butter, and pineapple, then spread out on a rimmed baking sheet and sprinkle with 1 teaspoon of the sea salt. Place the pan in the oven and broil for 3-6 minutes, keeping a close eye on the pork until it is crisp.
