The Oyster Blade (Marucha) – also known as Flat Iron Steak or Marucha in Argentina – is connected to the shoulder blade of the beef. Blade roast is highly marbled and juicy.
It is a very flavoursome cut that is versatile enough to be cooked whole as a roast, sliced into steaks and cooked on the barbecue or in a pan, thinly sliced for a stir-fry or diced for slow cooking in a braise or casserole. Second in tenderness to the Tenderloin, the Flat Iron is well-marbled, rich in flavor and juicy. Derived from the Chuck (Shoulder), the Flat Iron Steak has a great combination of rich beefy flavor, and a tender bite.
