This one's from Bon Appetit, God bless 'em. Since I've been doing extremely low carb, recipes like this are my salvation. Wrap it in a lettuce leaf instead of a tortilla- I won't say it's AS good, but it's pretty darn good.
It’s worth seeking out pork belly for the amazing texture it lends, but if you can’t get it, substitute with another pound of shoulder.
3 pounds boneless pork shoulder (Boston butt), cut into 1½-inch pieces
1 pound pork belly, cut into 1-inch pieces
1 cup homemade chicken stock or low-sodium chicken broth
1 tablespoon (heaping) kosher salt
1 teaspoon freshly ground black pepper
Warm corn tortillas, chopped white onion, lime wedges, sliced avocado, dried oregano, chopped cilantro, and shredded cabbage (for serving)
Place pork shoulder, pork belly, stock, salt, and pepper in a large heavy pot; cover and bring to a boil over medium-low. Reduce heat and simmer until pork is tender and shreds easily, about 2 hours. Uncover; cook 10 minutes to reduce liquid (but not completely). Remove from heat.
Transfer half of pork and pan juices to a large skillet, preferably nonstick, and cook over high until liquid evaporates and pork begins to fry in its rendered fat. Fry, stirring occasionally and pressing on pork with spoon to break up, until browned and just beginning to crisp, 10–15 minutes. Most of the pieces should be bite-size with some smaller shredded and super-crisp bits in the mix. Using a slotted spoon, transfer to a paper towel–lined baking sheet. Cover with foil to keep warm and moist. Repeat with remaining pork.
Serve carnitas with tortillas, onion, limes, avocado, herbs, and cabbage.
Do Ahead: Pork can be braised (do not fry) 3 days ahead. Cover and chill.
