OK, the follow up. Hope everyone had a Merry Christmas and a Big Thanks to everyone who posted to make this a very successful cook.
Pulled the beast out about 11PM on the 24th to get close to room temp. Have set up the WSM the night before with KBB and Hickory chunks. Had a Weber starter cube under a 1/3 full chimney of KBB. Target temp was 250*F smoker temp. My original plan was to be up at 6AM, light the smoker and prep the rib. Due to the consumption of adult beverages and good cheer the night before I managed to get moving around 7:45. The IT temp of the rib after setting out all night was only 58*F. Had to go with it as company was on the way at 1PM. Did not remove any fat cap and only went with ksalt and course ground pepper.
Went in, got cleaned up for company etc and temps were rock solid on the smoker and temp steadily climbing. Only took about 2 hours to hit target temp of 120*F.
Pulled and tented with foil to rest with the intention of a reverse sear on the gasser but the carryover temp kept rising so I wanted to see how high it would go. It climbed to 133*F after approx 45 mins. 135*F was my target temp IT so I called it good.
No brown edge on this one.
My plate.
This skinny Nephew ate all of that plate!
Take aways from this cook as follows:
1. Trimming fat closer next time.
2. Removing bones precook.
3. Researching prim rib carving.
4. Much easier and faster to smoke than brisket.
5. Farking super sharp carving knifes!
Man it was good. Going to enter the TD and Thanks for lookin'.
