Machaca Spanish: [maˈtʃaka] is a traditionally dried meat, usually spiced beef or pork, that is rehydrated and then used in popular local cuisine in Northern Mexico and the Southwestern United States. It is also readily available in many groceries and supermarkets in these areas. In areas where the dried meat product is not easy to obtain, slow-cooked roast beef (brisket) or skirt steak shredded and then fried is sometimes substituted.
