Beef Roast with Rosemary

serves 6. Heat oven to 500F. Put the rib roast in roasting pan, season with salt and pepper and rosemary, and sear in preheated oven for 15 minutes. Lower heat to 350F. and cook until internal temperature reaches 130F, about 1 1/4 hours, for medium-rare. Remove roast from oven, cover with a sheet of foil, and let rest for about 10 minutes. Put roast with ribs down on a cutting board and cut into thick or thin slices. For thin slices, cut meat off the ribs. For thick ones, cut between the ribs as necessary.
