The secreto is a small, hidden (“secret”) boneless cut from behind the shoulder. Tender, well-marbled & delicious, this is a great cut for quick cooking applications like searing or grilling.  It offers great flavor even when simply served seasoned with salt & pepper. Even though it’s cut from an entirely different part of the animal, secreto is sometimes referred to as “skirt steak” in the US, because it’s cooked similarly.
