I may be a little late for the party on this one but here goes. I did my first brisket flat this weekend. Put Jeff's rub all over it and put it in the smoker at 240. It took 10 hours and came out very good. Jeff's rub did not make it hot. I make that rub according to the directions and the brisket tasted wonderful. Again, no noticable heat. Smoked fat side up, did not foil and did not check it until the IT was 197. Covered and let stand for 2 hours.
