The secret to the Bradley Smoker is the Bradley Smoker Bisquettes. To produce the Bisquettes, hardwood smoker chips are bound together using precise quantities, at controlled pressures and densities, without additives. The flavor of the smoke is determined by the variety of smoker wood being burned.Designed for use with the Bradley Smoker, a flavor smoker Bisquette is burned once every 20 minutes producing a clean smoke flavor. Bisquettes produce smoke four times cleaner than smoke produced by identical smoker chips burnt in a fry pan or burn box. 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.When smoker wood burns, the smoke flavor is produced in the initial minutes of the burn. Wood smoking chips or sawdust, burnt for too long, impart a distinct after-taste to smoked food. The flavor would also be affected by fluctuating high temperatures, gases and resins. However, with the Bradley flavor Bisquettes, you get perfect results every time you smoke.
