About this cut
The Argentine Vacío is a legendary cut, prized for its unique structure of muscle fibers encased in a protective layer of fat and membrane. It offers a deep, beefy flavor profile that surpasses many loin cuts, providing a satisfying chew and incredible succulence when cooked patiently. This multi-layered piece is the cornerstone of the traditional asado, delivering a textural journey from the crispy exterior fat cap to the tender, juice-filled interior.
Taste-DNA
Located in the abdominal wall, this complex includes the M. obliquus internus abdominis and the M. transversus abdominis, characterized by long, coarse muscle fibers. The constant movement of these muscles translates into high myoglobin levels and intense flavor, requiring skillful heat management to soften the connective tissues.
Preparation
Cooking Guide
For the ultimate asado experience, cook the Vacío over medium embers for 60 to 90 minutes, starting with the fat side facing the heat to render and baste the meat. Maintain a consistent, gentle temperature to allow the internal connective tissues to soften, aiming for a medium core temperature of 54-56°C. Never trim the silver skin or fat before cooking, as these protect the meat from drying out. Rest the meat for at least 15 minutes before carving against the grain to ensure maximum tenderness.
