Skirt steak is a flavorful cut of beef that comes from the diaphragm area of the cow. It is known for its long, flat shape and pronounced grain, making it ideal for marinating and quick cooking methods like grilling or stir-frying. This cut is often used in dishes such as fajitas and stir-fries due to its rich taste and tenderness when cooked properly. Due to its texture, skirt steak is best cooked at high temperatures and served medium-rare to medium. It is typically sliced against the grain to enhance tenderness. This cut is popular in various cuisines, especially in Mexican and Argentinian dishes.
