Ingredients

• 5 pounds prime rib roast
• 1 tablespoon kosher salt

Instructions

1. 1 Gather all ingredients.
2. 2 Place beef on a pan, and rub with salt. Place meat on a rack or twisted foil so air can circulate under roast, and transfer to the fridge for 24 to 48 hours.
3. 3 Remove from the refrigerator and let it rest for a few hours to come to room temperature (optional).
4. 4 Preheat the oven to 300 degrees F (150 degrees C). Transfer roast into a roasting pan, preferably on a rack.
5. 5 Mix butter with coarse salt, pepper, and cayenne in a small bowl and spread onto the sides and top of the roast. Then add more salt to the top. Pour water into the bottom of the pan.
6. 6 Roast in the preheated oven until internal temperature is 115 to 120 degrees F (46 to 48 degrees C), about 1 hour and 20 minutes (about 20 minutes per pound). Remove from the oven, cover with foil and let rest for at least 20 minutes before serving.
7. 7 Drippings from the pan can be deglazed with broth or water, and served alongside meat.
