Sándwich de vacíoGrilled flank steak sandwich
Vacío, the flank cut with its layer of fat and membrane, is grilled slowly for a long time at Buenos Aires parrillas, and at the street grills near football grounds and the weekend fairs of Mataderos it ends up sliced into crusty bread for a hearty midday sandwich. Cooked gently, it turns tender and very juicy, with a crisp, salty layer of fat. Chef's tip: grill it membrane side down first for most of the time and do not trim that membrane off; it protects the meat and turns crisp.
