Menudo is a traditional Mexican soup made primarily from beef tripe, which is the stomach lining of cattle. It is typically seasoned with hominy, chili peppers, and various spices, giving it a rich and robust flavor. Menudo is often served with lime, onions, and cilantro, and is popular as a comforting dish, especially during celebrations or as a remedy for hangovers. The recipe can vary by region, with different families adding their unique twists.
