Step 1

For the tacos: Place pork in the freezer for 20 minutes. Using a sharp knife, cut pork into 1/2-inch (1 cm)-thick slices. Set aside in a bowl.

Step 2

For the pork marinade: In a blender or food processor, mix all ingredients until smooth. Pour over pork slices and marinate in the fridge for at least 1 hour and up to 24 hours.

Step 3

Preheat barbecue to high. Place pork on the grill and grill for 3 minutes on each side, or until you see some nice grill marks. Transfer pork to a cutting board and finely slice, al pastor–style.

Step 4

Serve in warm tortillas. Garnish with salsa verde, radishes, pineapple (if using), red onion and cilantro. Serve with lime wedges.
