This, we dry-aged prime rib for four days. We it in cheesecloth and placed it on a baking sheet in refrigerator for four days. On Christmas morning, we removed it from the fridge and allowed it to sit on the counter it room temperature.

Next, we coated with vegetable oil salt, and freshly cracked pepper on all sides, including the ends, a crust 

Now the baking process Ensure prime rib is bone side down. Bake the roast at degrees until the internal temperature reaches 118, approximately hours. Remove it from oven let rest until the internal temperature rises to 130 degrees, about 30 minutes. Pour the drippings from the baking sheet into a heat-safe. Return the roast to the oven, set at 500 degrees Fahrenheit, and cook until browned about 10 15 minutes. Our smoke alarm goes off every time we do this. Finally, remove the roast from the oven, carve, and serve.
