Beef Short Ribs (Asado de Tira)

Beef short ribs are cut from the junction of the beef chuck and rib primals, spanning ribs 6 through 8 and the chuck end. The cut divides into two fundamentally different preparations: English-cut (parallel to the bone, producing 2–4 inch segments) and flanken-cut or cross-cut (sliced across the bones into thin strips, ½–1 inch wide). This distinction is not merely cosmetic — it determines the entire cooking approach. English-cut ribs are thick and dense, requiring low-and-slow moisture to dissolve their heavy collagen into silky gelatin. Flanken-cut ribs cook quickly over high heat, caramelizing in minutes. Throughout Argentina, Uruguay, Chile, and Mexico, the flanken style is called Asado de Tira and forms the backbone of the parrillada tradition.

The short rib's defining characteristic is its extraordinary marbling and connective tissue. Intermuscular fat runs through the meat in visible streaks, while thick collagen sheaths surround muscle fibers. This composition makes short ribs punishing to the impatient cook — served rare like a steak, they are tough and chewy. But given sufficient time at low temperature with moisture present, the collagen hydrolyzes into rich, unctuous gelatin that enriches the braising liquid into a natural jus. The result is fork-tender meat that shreds cleanly and a sauce that coats the back of a spoon. No other cut delivers such dramatic transformation with relatively modest technique.

Argentine asado tradition demonstrates that short ribs need not always be braised. When cut thin (flanken-style) and grilled over wood or charcoal at high heat, the same primal produces a completely different result — charred at the edges, smoky, and intensely beefy in minutes rather than hours. Both approaches are valid; both are delicious. The cook's choice depends on the time available and the desired outcome.
