The secret to the Bradley Smoker is the Bradley flavor Bisquettes. To produce the bisquettes, the hardwood chippings are bound together using precise quantities, at controlled pressures and densities. The flavor of the smoke is determined by the variety of wood being burned. The Bradley Smoker burns a flavor bisquette once every 20 minutes producing a clean smoke flavor. As each is burnt, it is gently pushed from the burner element by the next bisquette, to be extinguished in the pot of water. The cycle continues for as long as the Bradley Smoker is loaded with bisquettes.
