Steps:
1. weight prime rib roast and multiply pounds by 5 for num ber of minutes to cook in 500 degree oven.
example: 5.5 pound prime rib X 5 = 27.5 minutes
2. let prime rib warm out of the fridge to room temperature. 6 hours or longer (very important to do this part)
3. soften butter and spread it thick over entire roast, add a lot of salt, pepper and your choice of herbs. I recommend Braggs Sprinkle.
4. place roast in center of 500 degree oven (bone side down) for specified above minutes.
5. once that time is up, turn the oven off and let the roast sit in the oven for 2 hours. DO NOT OPEN THE OVEN
6. enjoy
if there are some among you who do not like rare meat, have a hot cast iron skillet ready to sear the outsides of individual slices.
