Use the small end cut of prime rib. Have at room temperature. This recipe calls for the prime rib to be cooked several hours before you eat.
Start cooking between 12 and 1 pm if you are going to eat before 8 pm
Preheat oven to 400. Season. Cook for 15 minutes at 400 then turn down to 375 for 45 minutes.
Turn off oven and let roast sit in the oven. Remove roast from oven and let stand covered for 10 to 15 minutes then carve.
If you are cooking more than a 4lb rib roast (larger cut) preheat oven at 475 and cook for 1 minutes then turn down to 375 for 45 minutes
