I found a recipe on allrecipes. It was honestly the best brisket I ever had. We smoked it (fat side down) for 2 hours and then double wrapped it in aluminum and put it in our inside oven for another 2 hours. We let it sit out, wrapped for another 45 minutes.
Dang...... about 225 degrees until it is done...... If you want it nice and easy to pull, bring it to 195 degrees internal. It "usually" takes about 1.25 hours per pound at 225.
