Thanks all. It was SUPER easy to make and I'll definitely be doing it more often. I just wish the meat wasn't $10/lb.
This method beat any prime rib I've had at restaurants (high and low end). Now maybe what I need to do is invite some neighbors over for a sample. Then, I can offer to cook it for them (when they buy the meat). I'll do whatever it takes to maximize my new addiction here.
A quote from my mother-in-law at dinner was "I normally don't like prime rib, but I really like this prime rib you made. In fact, I think it's the best you've ever smoked in the past year.". FYI, I've owned my SI2 a little over a year now and they've sampled probably 10-15 of my smokes in that time period. This includes Turkey, Chicken, Ribs, Pulled Pork, Salmon, Bacon, etc...
