Prime Rib Roast

I bought one today at the Gordon Head Fairway, it was a very good deal.   I thought this would be a great dinner, but things have gotten in the way.

First off, two people will not be here for dinner
Second, I made a huge error on the cooking time and it is not done yet and I have to leave for a meeting in 15 minutes.

I will add a pic of the roast to this posting later tonight - which is what I am now doing

The roast was really rare when I pulled it out.   It was a screaming deal for a 7 pound standing rib roast, $40
