Tyler Florence's Horseradish and Garlic Prime Rib

This recipe uses lots of salt -- which I don't normally use much of. When I prepared it, I didn't add nearly as much salt -- probably a couple of tbsps. If I didn't want to use the juices, I would use the amount of salt Tyler calls for.

• Ready In: 2 hrs 20 mins
• Serves: 6-8

Ingredients

• 1 (6 lb)  prime rib roast, 3-ribs
• 5  garlic cloves, smashed
• 1⁄2 cup  prepared horseradish
• 1⁄2 cup sea salt
• 1⁄4 cup fresh ground black pepper
• 1⁄2 cup extra virgin olive oil

Directions

1. Preheat the oven to 350 degrees F.
2. Lay the beef in a large roasting pan with the bone side down. (The ribs act as a natural roasting rack.).
3. In a small bowl mash together the garlic, horseradish, salt, pepper, and olive oil to make a paste.
4. Massage the paste generously over the entire roast.
5. Put the pan in the oven and roast the beef for about 1 1/2 to 2 hours for medium-rare (or approximately 20 minutes per pound).
6. Check the internal temperature of the roast in several places with an instant-read thermometer; it should register 125 degrees F. for medium-rare.
7. Remove the beef to a carving board and let it rest for 20 minutes. The internal temperature of the meat will continue to rise by about 10 degrees.
8. Pour the pan juices into a fat separator or small bowl and set aside to allow the fat and beef juices to separate. Pour off and discard the fat. Use the juices to pour over the sliced meat if desired.
