Perfect Prime Rib
This recipe works for prime rib roasts any size from 2 ribs to 6 ribs. Plan on 1 pound of bone-in roast per guest (each rib adds 1.5 to 2 pounds to the roast). For best results, use a dry-aged, prime grade or grass-fed roast.
To further improve the crust, allow it to air-dry, uncovered in the refrigerator on a rack overnight before roasting. Seasoning with salt up to a day in advance will help the seasoning penetrate the meat more deeply. If timing goes off and your roast is ready long before your guests are, the roast can be re-heated by placing in a 200°F oven for 45 minutes before continuing with step 2.
