Smoking my first prime rib roast tomorrow and don't want to screw it up... It's 7.9#. We are leaving for a one hour chruch service at 5p and I want to pull it at 4:30 and finish it in the oven when we return from church. My questions are.... Assuming I keep steady at 275, how early should I target to start: what temp should I target to pull it at: what temp should I finish in the oven at for how long: Thanks in advance for any help. I'll post after the fact to let you know how it turns out. EDIT Adding qview, so we'll see how it looks..
