Clean egg out. Fill with large chunks of lump, no small trash. Light up one side, put several large wood chunks in middle with all dampers open, let burn for ten minutes then close butterfly and bottom damper half way. Place deep aluminum roasting pan with couple inches of water on grill, set V rack in pan. When temp hits 250, place seasoned meat on rack.Crack both dampers to 1/4 inch +- so temp holds around 210. Add water as needed. Will take around 16 to 18 hours to cook a 15lb piece of meat. Save juice water to make sauce.
