- 4 pound beef short ribs, cut across the ribs into 1 1/2-inch thick slices
- Kosher or fine sea salt and freshly ground black pepper
- 2 tablespoons red wine vinegar
- Tomatillo Salsa
Trim any surface fat from the ribs. Rub all surfaces of the meat generously with salt and pepper. Put the ribs into a large baking dish that fits them all in a single layer. Drizzle the vinegar over the ribs and turn them over so they have vinegar on both sides. Let the ribs marinate, turning them occasionally at room temperature for up to 1 hour or in the refrigerator for up to 4 hours. (This longer marinating time may make the surface of the ribs turns grayish-white in spots. That is fine and the discoloration will disappear when they are grilled.)
Heat a gas grill to medium-high or build a strong charcoal fire.
Grill the ribs, turning them once, until well browned, even charred here and there, about 6 minutes per side. The ribs should be just a touch rarer than medium-anything less and they will be very chewy. Let them rest 4 to 5 minutes before serving.
