Step 1: Prepare the Marinade - In a food processor, combine the extra virgin olive oil, cilantro, orange zest, fresh orange juice, lime juice, mint leaves, garlic cloves, fresh oregano, ground cumin, salt, and black pepper. Pulse until finely chopped and well blended.

Step 2: Marinate the Pork - Place the pork shoulder or butt into a large ziplock bag and pour the marinade over it, ensuring the meat is thoroughly coated. Seal the bag, pressing out as much air as possible, and refrigerate overnight.

Step 3: Rest the Pork - Remove the pork from the refrigerator about 1 hour before cooking, allowing it to come to room temperature. Preheat your oven to 220°C (425°F).

Step 4: Initial Roasting - Place the marinated pork in a roasting pan and roast uncovered for 30 minutes.

Step 5: Continue Roasting - After 30 minutes, reduce the oven temperature to 190°C (375°F) and continue roasting for an additional 1.5 to 2 hours, basting every 30 minutes.

Step 6: Shred for Pulled Pork (optional) - Lower the temperature to 160°C (320°F) and roast for 3.5 hours for a pulled pork version.

Step 7: Rest the Meat - After roasting, remove the pork from the oven and cover loosely with foil. Allow it to rest for about 20 minutes.

Step 8: Serve and Enjoy - Carve or shred the pork according to your preference, and serve with your favorite sides.
