The ink, glue, and recycled materials in paper bags can emit toxic fumes when they are exposed to heat. Instead, use purchased oven cooking bags. Cooking is by indirect heat and is accomplished with a covered outdoor grill or smoker. Instead, a pan of water is placed beneath the grilling surface to catch the fat and juices which drip from the turkey as it cooks. This prevents a flame up which could burn the turkey.
Cooking is by smoky, hot air.
Turkeys 16 pounds or less are recommended for safe smoking. Do not stuff the turkey. To grill, start with clean equipment and a good quality charcoal. Build a pyramid of charcoal to one side, ignite the charcoal and let the coals get red hot. Carefully push the hot coals evenly around the edge and position the grill rack above.
