     1/4  cup           corn oil
     1/4  cup           melted butter
     1/4  cup           onion -- minced

Preparation:

Combine oil, butter, onion, garlic, annatto, cumin, lemon and orange juices in a large shallow pan. Add chicken halves, turning to coat well. Cover and marinate several hours, or overnight. Remove chicken from marinade, then cook over medium coals on barbecue grill, or in a broiler 4 inches under source of heat, until browned on both sides and meat is done, turning and basting frequently, about 25 minutes. Cut chicken halves into pieces. Serve with beans and rice, corn or flour tortillas, and fresh salsa.
