This right up my alley!
I never start one frozen so I can't say yes or no but I'd bet it wouldn't work the way you want it to.
I start by rubbing the butt with CYM then my rub, I start the SRG on high top down for 15 mins to get the pellets going good (I do use the Tommy Ring
) I set the basket in the chamber and let it go another 15 min's to start a good bark then turn to low and top down . after 4 hrs I check
IT Now this is for butts 7 lbs and up . If doing a smaller butt I ck
IT at the 3 hr mark. I pull at 200 to 205
IT foil and set them in my Cambro holder (any cooler would work) for 2 hrs then remove and pull.
You will have a stall around 165 to 170 but it won't last long
Hey it was good enough for 7th place at a cook off going up against BGE's and wood burners
If not enough info let me know, I know infrared butts!
