Generously season the brisket with the seasoning.
Leave the fat cap intact and season it as well.
Let marinate a minumum of one hour or overnight. Build a fire with good quality charcoal and well seasoned pecan wood.
Let burn at least 30 minutes to burn off the lighter fluid fumes and start a good bed of coals.
Place brisket away from direct heat and cook 3 hours at 250 degrees F.
After three hours wrap brisket securely in heavy aluminum foil.
Baste with Bar-B-Q Sauce.
Continue cooking for an additional 3 hours at approximately 325 to 350℉ (180℃).
To serve remove fat cap and slice across the grain for the tenderest portions.
