Ingredients

• 1 (4-rib) standing beef rib roast (bone-in prime rib; 9 to 10 pounds), at room temperature 1 hour
• 2 tablespoons extra-virgin olive oil
• 3 tablespoons kosher salt
• 1/3 cup mixed peppercorns (pink, white, and green)

Instructions

1. Preheat oven to 450°F with rack in middle.
2. Rub roast all over with oil, then sprinkle all over with kosher salt. Coarsely crush peppercorns in a folded kitchen towel (not terry cloth) with a meat pounder or bottom of a heavy skillet. Coat meat on all sides with peppercorns, pressing to help them adhere.
3. Roast on a rack in a 13- by 9-inch roasting pan 20 minutes. Reduce oven temperature to 350°F and roast until an instant-read thermometer inserted into center of meat (do not touch bone) registers 110°F, 1 1/2 to 2 hours more. Transfer to platter and let rest, uncovered, 30 minutes (temperature of meat will rise to about 130°F for medium-rare).◊
