I have been wanting to make a prime rib for years but never shelled out the cash for one. Well the in-laws are coming for Xmas and we were talking about prime rib this weekend and I said I would smoke one if they wanted. They jumped on that and said "We'll buy the meat if you smoke it". I jumped all over that suggestion. I can't wait! One question since I have never made it. How many lb's of meat do you think I need for 6 adults and still have a bit left for leftovers the next day? I was thinking 6 of us could probably finish off a 5 lb one that night so I was thinking if we want leftovers it needs to be 8-10lbs. What do you think?? I'm looking forward to posting this smoke. I can't wait for next Sunday.
