Chitterlings, also known as chitlins, are the small intestines of domestic animals, usually pigs. They are a traditional Southern dish and are part of the culinary tradition of soul food. Chitlins are usually boiled down, fried up, and served with apple cider vinegar and hot sauce. They have a strong, pungent smell, which is heightened when cooking, and onions are often used in the cooking process to make the smell less strong. Chitlins are a delicacy that is enjoyed in parts of the Caribbean, Latin America, and Western Europe. They are also used in French cuisine, where they are called les tricandilles and are grilled until crispy or used as casings for sausages. Chitlins are labor-intensive to clean and prepare, so they are often reserved for special occasions.
