Abstract: An apparatus is disclosed for producing flavored smoke on an outdoor grill. The apparatus comprises a smoker that includes a container and a tortuous path. The tortuous path is devised such that certain ratios between different flow areas and volumes fall within specified ranges. Container characteristics include angled outer walls, reinforcing brace, and notched bottom. The container holds an airborne effluent source with the tortuous path enclosing the container. The tortuous path is formed through layers of non-aligned openings that allow the airborne effluent to vent from the container. The smoker may include a baffle and a raised lid cover. The raised lid cover is formed to collect undesirable wood tars.
