I used this recipe just last night and it was the best prime rib roast that I have ever cooked! I've cooked countless prime rib roasts and never have they turned out this good!!! I'm a far cry from a professional cook, but this recipe made me a star last night! I cooked a 4lb roast at 425 degrees for 1hr & ten minutes. Removed it from the oven when the internal temp was approx 120 degrees, then let it "tent" for 45 minutes. The end result was a perfect medium rare prime rib, with the outside pieces being more "medium" Exactly what I was after, since my husband enjoys it "medium" cooked. I was lucky to have enough drippings to make gravy, so perhaps the cut had a little more fat to it. Delicious, Delicious, Delicious!!!! I would encourage more people to try this recipe, you won't be disappointed. Thank you Barbara for sharing this fabulous recipe!
