Easy Rib Roast with Horseradish Sauce

Cooked up a special dish for family with the help of William, Benjamin, and Emily. I love this technique for cooking rib roast. The horseradish sauce recipe can scale down (we needed every bit of what we made).
Ingredients:
1 bone-in rib roast (if using boneless, tie up with butcher's twine)
3/4 cup unsalted butter, softened
kosher salt
3 tablespoons crushed black pepper
3 teaspoons herbs de provence or rosemary

Directions:
1. Preheat oven to 500F. Generously salt the outside of the rib roast and let sit for 10 minutes.
2. Mix pepper and spices in the softened butter until well incorporated.
3. Pat moisture off of the rib roast and place in a deep roasting dish bone side down (fat side up). Coat the outside of the roast with the butter/spice mixture.
4. Put roast uncovered in the oven and cook at 500F using the following formula: weight of the roast times 5 equals the number of minutes to cook at 500F. For example, I cooked my 11 pound roast for 55 minutes. When you reach the time, turn oven off and leave the roast for 2 hours. Oven will gradually cool and the roast will slowly continue cooking. Don't open the door no matter how tempting it is!
5. Remove roast from oven after 2 hours and cut the bone away from the roast. Cut into 1/2 inch slices and serve with au jus and/or horseradish sauce.
Additional technique: Better to under cook it than over cook the roast. If it's less done than you like, have a pot of au jus at a low simmer on the stovetop. Dip your prime rib in this sauce and simmer for a minute. Remove when it's cooked as you prefer.

Ingredients for horseradish sauce:
