Generously marbled, and easy to prepare, a prime rib roast of beef makes an impressive centerpiece for any occasion. Also known as a standing rib roast, the cut is best roasted whole "standing" on its ribs, allowing the top layer of fat to render and self-baste the meat. Hand selected for our Butcher Shop by Double R Ranch, this roast has the perfect combination of flavor and tenderness. Large Roast: approx. 8 lb. (serves 8-10). Small Roast: approx. 6 1/2 lb. (serves 6-8). Shipped frozen. Product of USA.
