Preparation Preheat oven to 450°F with rack in middle. 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. 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).◊
