This looked like it had good marbling so i figured i'd take it to just before pulling and slice it like a brisket.
I cooked it catching the drippings on the bottom mini rack and added some veggies part way through. When the veggies were tender i pulled them and finished the chuckie to 190 IT.
Ok time for some slicing! Drip some au jus back over the slices....oh my!
