Hello, planning to do a bone in prime rib this weekend. I'll be doing it in my bbq guru onyx oven. My questions are, should I use a water pan in the process? And what is the best charcoal and smoke wood combination? I been having bad luck with cowboy brand lump charcoal. I hear white oak is great with prime rib? I have read quite a few posts about prime rib on the forum and have the Temps and times in mind. Just curious about these other things. Thanks.
