#1 Salt roast and let sit at room temperature. Roast should be brought close to room temperature before they go into the oven to ensure more even cooking.
#2 Preheat your oven to 500 farenheit. Pat the roast dry with paper towels (pre-salting should have made the roast release some moisture), and sprinkle the roast all over with salt and pepper.
#3 Place the roast fat side up and rib bones down in a roasting pan. Insert a meat thermometer into the thickest part of the roast, making sure the thermometer isn't touching a bone.
#4 Brown the roast at a 500 farenheit temperature in the oven for 15 minutes.
#5 Reduce the oven temperature to 350 farenheit. To figure out the total cooking time, allow about 11-12 minutes per pound for rare and 13-15 minutes per pound for medium rare. .
125 - 130 farenheit = Rare
135 - 140 farenheit = Medium Rare
145 - 150 farenheit = Medium
155 farenheit = Medium Well
165 farenheit = Well Done
