If you love the efficiency of gas grilling but long for the smoky flavor of charcoal, our smoker box is destined to become your favorite grilling accessory. Can be filled with aromatic wood chips or fragrant herbs for all kinds of smoky flavor infusions. Just soak your chips, place them in the base of the smoker box and then preheat the box on an outdoor grill. To smoke select foods, place ingredients on the perforated tray, set over the base on the grill and cover with the lid. To turn your entire closed grill into a smoker, remove the lid altogether. Made of heavy-gauge stainless steel. Dishwasher safe. A Williams-Sonoma exclusive.
