Prime Rib for Christmas dinner - I've read all of the previous posts and links which were great help but I still have some questions. Experience seems split on roasting indirect at 350 or low and slow at 250 and then searing before or after. So I'm comfortable either will produce great results. How about smoke? Do you add wood chunks? If so what flavor? I'm also thinking of having it deboned but then reattaching it to the rack for cooking. Any idea on how much time that adds to cooking rate?
