Menudo is a traditional Mexican soup made with cows stomach (tripe) in broth with a red chili pepper base. Hominy, lime, onions, and oregano are used to season the broth). Menudo takes a long time to prepare as the tripe takes hours to cook. It includes many ingredients and side dishes, and is garnished with chopped onions, chiles, cilantro, and often with lime juice. It is often prepared communally and eaten at a feast). There are many regional variations of menudo. In northern Mexico, hominy is typically added. In northwest states such as Sinaloa and Sonora, usually only the blanco (white) variation is seen; menudo blanco is the same dish, but red pepper is not added, thus giving the broth a clear or white color. Adding patas (beef or pigs feet) to the stew is popular in the United States).
