To make this Arroz Moros Recipe gluten free, use certified gluten-free chicken bouillon cubes, sazón with achiote, adobo seasoning, tomato sauce, and canned red kidney beans. Some seasoning blends and bouillon cubes may contain wheat-based additives, so verify all labels carefully. Use plain long-grain white rice and avoid shared scoops, pots, or utensils that may have touched gluten-containing foods. Prepare the dish on clean surfaces to prevent cross-contact.
