A steak (from Old Norse steik, “roast”) is generally a cut of meat or fish cut perpendicular to the muscle fibers, or of fish cut perpendicular to the spine. Meat steaks are usually grilled, pan-fried, or broiled, while fish steaks may also be baked.
Steak can also be meat cooked in sauce, such as steak and kidney pie, or minced meat formed into a steak shape, such as Salisbury steak and hamburger steak.
Without qualification, the word “steak” generally refers to beefsteak. Steaks from other animals are usually qualified as, e.g., ‘swordfish steak’ or ‘venison steak’.
