Ingredients

Instructions

  1. Step 1: In a large bowl, combine 2 tbsp chili powder, 1 tbsp ground cumin, 4 minced garlic cloves, 1/4 cup lime juice, 1/4 cup orange juice, 1 1/2 tsp salt, and 1 tsp black pepper. Add 2 lbs pork shoulder chunks and toss to coat. Cover and marinate in the refrigerator for at least 1 hour.
  2. Step 2: Place the marinated pork and all marinade into a slow cooker. Cook on low for 8 hours until pork is very tender and shreds easily.
  3. Step 3: While pork cooks, make quick pickled onions: combine 1/2 cup white vinegar, 1/2 cup water, 1 tbsp sugar, and a pinch of salt in a saucepan. Bring to a simmer, then pour over 1 thinly sliced small red onion in a jar. Let sit at room temperature for at least 30 minutes.
  4. Step 4: When pork is done, shred it with two forks and heat 2 tbsp vegetable oil in a large skillet over medium-high heat. Add shredded pork and cook for 5 minutes, stirring occasionally, until edges get crispy.
  5. Step 5: Warm 8 small corn tortillas on a dry skillet or microwave. Divide crispy carnitas among tortillas and top with pickled red onions and 1/4 cup chopped fresh cilantro. Serve with lime wedges if desired.
