"I know my way around the kitchen pretty well but was a bit thrown off by the size of roast I needed to do. 8 1/2 # worried me. Rib roast is way too expensive to fowl up.. I checked out a few ideas and have been pleased with Pauls's recipes before so after reading the reviews I went with it. I must say that it was so easy I could not imagine and without a doubt the best roast I ever cooked. My family was really impressed.
I did add 15 min to the initial cooking time because of the size but everything else as directed and it really was great.
