Started my first brisket this morning. It is a 5.75# flat from Costco. Trimmed a bit of fat off the top, used a rub called Steak Saver that I had laying around, no mustard. Set up indirect with a drip pan and platesetter with legs up. Have the Maverick on, and grid temp to start was 280F and dome was 250. Although I knocked things down a bit and grid has dropped to 268F so will need to go double check.
