Tacos de carne asada

Carne asada is grilled and sliced beef, usually skirt steak, flap steak, or flank steak though chuck steak can also be used. It is usually marinated then grilled or seared to impart a charred flavor. Carne asada can be served on its own or as an ingredient in other dishes. The term carne asada is used in Latin America and refers to the style of grilled meat in those countries. In South America, the term used for grilled meat is asado and it has a different style and preparation. Carne ranchera can be purchased from meat markets either prepared (preparada, i.e., already marinated) or not (no preparada), for marinating at home. The meat is characteristically marinated in lime juice, salt, and Mexican seasonings, but may also be simply rubbed with salt or spice rubs such as lemon pepper, before grilled. After grilling it is typically chopped for filling tacos and burritos, which also minimizes toughness. Once grilled, it is called carne asada.
