The AtlasTapa de Asado (Rib Cap / Spinalis Dorsi)
intensely flavored · heavily marbled · rich fat · premium
About this cut
Widely regarded by connoisseurs as the single most flavorful muscle on the entire steer, the Tapa de Asado or Ribeye Cap is the crown jewel of the rib primal. It boasts an extraordinary degree of intramuscular fat and a loose, pebbly grain that results in a melt-in-the-mouth texture unlike any other cut. This muscle combines the buttery tenderness of a filet with the deep, beefy intensity of a ribeye, making it a pinnacle of luxury butchery.
Taste-DNA
The Spinalis dorsi muscle sits as a curved cap over the eye of the rib (Longissimus dorsi) from the 6th to the 12th rib. Its position and lack of significant weight-bearing activity allow for extreme marbling and exceptional tenderness.
Preparation
Cooking Guide
To maximize the Spinalis dorsi, a high-heat sear is essential to trigger the Maillard reaction and render the heavy marbling. Aim for a medium-rare finish with a core temperature of 52-54°C, as the high fat content requires heat to become palatable but the loose fibers can toughen if overcooked. Resting is critical for at least 8-10 minutes to allow the pressurized juices to redistribute through the rich grain.
Core Temperatures
Portions per Person
Known as the 'crown' of the ribeye, its decadent fat profile demands a wine with significant structural tannins and dark fruit acidity, such as a powerful Cahors Malbec or a high-altitude Mendoza bottling.
