What is the name of the taco filled with dried, shredded beef, a specialty of northern Mexico?

The taco filled with dried, shredded beef, a specialty of northern Mexico, is called tacos de machaca.

Machaca is traditionally beef or pork that has been salted, spiced, dried, and later rehydrated and shredded. Drying preserved meat before refrigeration, making it especially practical in northern Mexico’s ranching and frontier communities.

The filling is commonly cooked with onions, tomatoes, and green chiles, then served in tortillas. In northern Mexico, flour tortillas are particularly associated with machaca, while restaurants in the southwestern United States may use the name for freshly cooked, shredded beef when dried meat is unavailable.

A related dish is machacado con huevo, in which the shredded beef is scrambled with eggs. The terms carne seca and machacado overlap regionally, but carne asada means grilled beef, not the dried-meat preparation. Deshebrada generally refers to shredded meat without specifically implying the dried, preserved style.
