To turn a kettle charcoal grill into a smoker, you can use the "snake method," where a low mound of just 3 or 4 unlit briquettes is arranged (like a snake) around the perimeter of the grill base. A small amount of hot, pre-lit briquettes is added at one end of the snake. The lit coals slowly and steadily ignite the adjacent unlit coals all the way down the line, producing a consistent, steady temperature. By placing wood chips or chunks on top of the unlit coals at regular intervals when setting it all up, you can also generate flavorful smoke throughout the process.
