• 2 lbs pork shoulder
• 2 peppers plus 2 tbsp sauce chipotle peppers in adobo sauce
• 4, minced garlic cloves
• 1 tsp ground cumin
• 1 tsp dried oregano
• 1 1/2 tsp salt
• 1/2 tsp black pepper
• 2 tbsp lime juice
• 12 small corn tortillas
• 1 medium, thinly sliced red onion
• 1/2 cup white vinegar
• 1 tbsp sugar
• 1/2 cup water
• 1/4 cup chopped fresh cilantro

Instructions

1. Step 1: Combine 2 chipotle peppers, 2 tbsp adobo sauce, 4 minced garlic cloves, 1 tsp ground cumin, 1 tsp dried oregano, 1 1/2 tsp salt, 1/2 tsp black pepper, and 2 tbsp lime juice in a blender and pulse until smooth to create a marinade.
2. Step 2: Rub the marinade all over 2 lbs pork shoulder, cover tightly, and refrigerate for at least 2 hours or overnight for best flavor.
3. Step 3: Place the marinated pork shoulder in a slow cooker and cook on low for 8 hours until the meat is tender and shreddable.

5. Step 5: Warm 12 small corn tortillas in a dry skillet over medium heat for 30 seconds per side until pliable and slightly charred.
6. Step 6: Shred the cooked pork with two forks and pile onto the warmed tortillas, then top with pickled onions and 1/4 cup chopped fresh cilantro before serving.
