Food Network offers a recipe for pork carnitas tacos, and Food and Wine offers a recipe for tacos al pastor. The pork carnitas recipe involves braising a pork butt with herbs and vegetables for several hours, while the al pastor recipe involves grilling marinated pork with pineapple and onion.
Food Network's recipe calls for fresh thyme, garlic, bay leaves, lime and orange juice, and kosher salt. Braise a boneless pork butt cut into 2-inch chunks along with all the ingredients and water for about three hours, then turn the heat to high to brown the pork. The recipe suggests serving the tender pork on warm corn tortillas with pickled red onions. The full recipe with ingredient amounts and step-by-step instructions is available at FoodNetwork.com.
The Food and Wine recipe makes a marinade with garlic, oregano, cumin, pepper, cloves and guajillo chiles. Blend the ingredients with pineapple juice, vinegar and achiote paste and set in a container with sliced pork butt to marinate in a refrigerator overnight. Grill sliced pineapple and onion, then grill the marinated pork over high heat. Cut the pineapple, onion and pork together and serve atop corn tortillas with chopped cilantro and lime wedges.
