This is how it went yesterday.
Outside temp=18, wind probably 8-10 mph.
Started grill @ 12:00, set to 225, let her chug (just perfectly, I might add) till 1:00, controller would rock between 222 to 227.
Roast on at 1:00, surface temp approx. 60, one hour out of fridge.
Every half hour I spun the roast (not turned) 1/4 turn, dead center of the pit, lid open, lid shut, no dilly dallying.
3:15 was 1st probe, it was 108, dead center of roast, gentle in and gentle out.
3:45 2nd poke, it was 118.
Pulled it at 4:00, It was 122.2 (forgot to say that) straight upstairs, no more pokes, 5 minute rest uncovered on the cutting board, that was all the rest it saw.
Plated it with my wife's homemade fettucini alfredo, (dang near upstaged me with this), homemade cranberry something kind of salad (also very good), slow pit warmed store ham with a bourbon, brown sugar maple glaze (son in laws favorite) and fresh salad with homemade blue cheese.
Looking for plated pictures but we have them on 4 different phones, 2 I pads etc. might take me a bit.
The roast was incredible, cooked faster than I would have thought, I truly would have cooked this rascal straight to where the devil lives if I hadn't have heeded that Bentley tidbit.
The tenderness was truly unbelievable, the flavor was very rich and beefy, not over powering although I am glad I pulled it and vac sealed at 21 days.
My wife WILL not eat prime rib, never has in 30 years, I gave up.
My Daughter and Son-in-law loved it but my son in law had to take his to med. well, dumb kid, he pan seared it, I told him I aint ruining it for you.
My daughter who has eaten my cooking for years said we did make the right call by going 21 days, I could have gone another week but this is an excellent point of reference for me in the future.
I can honestly say I did my best to follow to the "T" what info I was offered and it was spot on.
For those who like me have always wanted to try it, I say this, "pull the trigger" you have no reason not to, there is a wealth of info here and you saw how forthcoming it was.
I was scared as heck going into this, now I just realize how foolish it was of me to wait so long.
Merry Late Christmas and ours was clearly one for the record books, first Grandbaby gets the credit.
This adventure will be repeated, it was fun as heck.
