Kittencal's Perfect Prime Rib Roast Beef

NOTE...THE INTERNAL TEMPERATURE NOT THE TIME IS YOUR BEST GUARANTEE FOR DONENESS so for a perfectly cooked prime rib roast invest in a meat thermometer and you will never go wrong with this recipe! --- if desired you may omit the au jus and just serve the roast, I prefer to make the au jus especially if I am serving this at a holiday table --- use nothing else but only fresh garlic, a little salt and lots of fresh ground black pepper for this or you could use 1 teaspoon garlic salt, using any other spices will take away the flavor, nothing else is needed --- cooking on very high heat then reducing the temperature will seal in all the meat juices to produce the most tender and flavorful prime rib, this actually is the method that a lot of the higher end restaurants use to make there prime rib and is the method I always use when I make prime rib roast at my home --- the cooking time stated on the recipe is for a 3-4 pound prime rib, you can use this method for a larger prime rib and increase the cooking time please see bottom of directions --- for a perfectly cooked prime rib roast a meat thermometer inserted in the roast should read about 140 degrees for medium-rare doneness, it is advised not to cook prime rib more that medium-rare ----- using more that the specified amount of salt will draw out the juices from the roast, you could add a little more but it is best to salt the meat after it is cooked, using a minimum amount of salt will insure a juicy tender prime rib roast, 1 teaspoon or less of salt will be fine, remember to remove your roast from the fridge about 2 hours before cooking --- also see my recipe#146196 this is a must served with prime rib!
