1. Rinse the fish and pat dry; score both sides with 2–3 diagonal cuts about 1/2 inch (1.27 cm) deep to help seasoning penetrate. 2. In a small bowl, mix lime juice, oil, annatto (if using), crushed garlic, salt, and pepper to make a loose marinade. 3. Rub the marinade all over the fish and into the scored cuts, and inside the cavity if whole; let rest 20–30 minutes at room temperature (or up to 1 hour refrigerated). 4. Prepare a hot charcoal grill set for direct medium-high heat; oil the grill grate well to prevent sticking. 5. Place the fish on the grill over medium-hot coals, cook 6–8 minutes per side for a 3 lb (1.36 kg) fish, turning carefully once, until the skin is crisp and flesh flakes easily with a fork (internal temperature 140–145°F / 60–63°C). 6. Transfer to a board, sprinkle with chopped cilantro and green onion, and serve hot with lime wedges.
