Flank steak is a cut of beef taken from the lower chest or abdominal area of the cow. It is known for its rich flavor and relatively lean texture, making it a popular choice for grilling and marinating. This cut is typically long and flat, with a pronounced grain that runs along its length. Due to its toughness, flank steak is best cooked quickly over high heat, such as on a grill or in a skillet. It is often sliced against the grain to enhance tenderness. Common dishes featuring flank steak include fajitas and stir-fries, where its flavor can shine through.
