Brazilian Beef Flank Steak (500-1000g)
Flank is the leanest of the two. It's a good all-purpose beef cut, suitable for grilling, roasting, broiling, or sautéing. But because it's so lean, it can be dry and tough if overcooked or sliced too thickly—it's important to cook flank to no more than medium and slice it very thinly against the grain
Flank steak needs to be marinated or braised to increase tenderness. Marinating flank steak with an acid such as citrus or vinegar chemically breaks down the tough muscle fibers to produce tender steak. Marinating also imparts tons of flavor.
