Decided to BBQ a beef brisket using my COBB. I cut the brisket in half, rubbed it in mustard and spiced it. Covered two on the holes of the holes on the cover using foil. I cooked it using Kingsford charcoal for 3 hours, opened it up and added more charcoal and water. An hour later (4 hours into the cook) I wrapped it in foil with a little water and spices added to it. I cooked it for another 2 hours, for a total of 6 hours. Let it rest for 30 minutes. It came out super moist and tender, with a nice smoke ring.
