01 - Place green onions, Scotch bonnet peppers, garlic, onion, thyme, brown sugar, allspice, cinnamon, nutmeg, black pepper, salt, soy sauce, vegetable oil, lime juice, orange juice, vinegar, and parsley in a blender. Blend until completely smooth and fragrant, scraping down sides as needed.
02 - Pat chicken pieces thoroughly dry with paper towels. Transfer to a large bowl or sealable plastic bag. Pour marinade over chicken, massaging to ensure every piece is evenly coated. Seal and refrigerate for minimum 4 hours, preferably overnight for maximum flavor penetration.
03 - Preheat grill to medium-high heat, approximately 375°F. Charcoal grill recommended for authentic smoky flavor. If using gas grill, add wood chips for additional smoke.
04 - Remove chicken from marinade, allowing excess to drip off. Place on preheated grill, skin-side down. Cook for 40-45 minutes, turning every 10-12 minutes and basting with reserved marinade during first half of cooking. Chicken is done when internal temperature reaches 165°F and exterior shows charred, crispy edges.
05 - Transfer grilled chicken to cutting board or platter. Let rest for 5 minutes to allow juices to redistribute. Serve hot with traditional rice and peas, fried plantains, or coleslaw.
