The pellet grill, or more accurately, the pellet smoker, is a cooker that uses pellets of compressed sawdust—rather than conventional wood or charcoal—to generate heat and smoke. Some models, like the Traeger pellet grill, use a thermostatically controlled metal heating rod to ignite the pellets, giving you accurate, turn-of-a-knob heat control. Kansas City barbecue legend John Willingham used a custom designed pellet cooker to win multiple Grand Championships at the Memphis in May World Championship Barbecue Cooking Contest (one of his cookers resides at the Smithsonian Institution).
