Instant Pot Carnitas

In the bowl of a multicooker, toss together pork, chiles, 4 teaspoons salt, oregano, cumin, and cayenne. Add orange and lime juices, onion, garlic, and 1 cup water. Secure lid of multicooker. Cook on "Meat/Stew" setting for 50 minutes. Once time is complete, allow pressure to release naturally. Carefully remove lid. Discard onions and garlic. In the bowl of the multicooker, use two forks to shred pork into bite-size pieces.

Using tongs, place a tortilla directly on a gas flame or in a heavy skillet over high heat. Cook, flipping once, until lightly toasted and charred in places, about 30 seconds. Wrap in a clean kitchen towel. Repeat with remaining tortillas. Serve carnitas in tortillas with cabbage, avocado, cilantro, cheese, and a squeeze of lime.
