Machaca
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 or skirt steak shredded and then fried is sometimes substituted. The dish is known primarily in the north of Mexico, and the southern regions of the U.S. states of Arizona, California, and New Mexico, and in Texas where it is known as machacado. In central and southern Mexico, it is not well known by lower socioeconomic classes. Machaca was originally prepared most commonly from dried, spiced beef or pork, and then rehydrated and pounded to make it tender. The reconstituted meat would then be used to prepare any number of dishes. While drying meat is one of the oldest forms of preservation, the drying of beef with chilis and other native spices was developed by the ranchers and cowboys of northern Mexico.
