Tripas

Tripas or machitos is a popular Mexican dish consisting of pig or cow intestines. It is mostly used as a filling for tacos, so tripas can be found throughout Mexico, usually at taco stands, and especially in open-air markets called tianguis. Boiled and grilled, tripe is commonly topped with chopped onions, coriander, and spicy chili sauces. The preparation of tripas requires a great deal of knowledge because they shouldn't be overcooked nor undercooked, as it makes them hard to chew.
