The secret to the Bradley Smoker is the Bradley Flavour Bisquettes. To produce the bisquettes, the hardwood chippings are bound together using precise quantities, at controlled pressures & densities. The flavour of the smoke is determined by the variety of wood being burned. When wood burns the smoke flavour is produced in the initial minutes of the burn. Once the wood generates enough heat to keep burning on its own, it yields high temperatures, acids, resins & gases. These will distort the flavour & the appearance of smoked food. When wood burns to this stage there is no control over the cooking conditions. With Bradley Flavour Bisquettes the guesswork is eliminated. Not only do Bradley Flavour Bisquettes eliminate unwanted heat, smoke produced the Bradley way is four times cleaner than smoke produced by identical loose chips burned in a fry-pan or burn-box. The Bradley Smoker consumes bisquettes at the rate of Approx. one every 20 minutes. Operating costs of the smoker are therefore less than 1 per hour. The Bradley Smoker burns a flavour bisquette once every 20 minutes producing a clean smoke flavour. 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. Flavours Available Apple (48 per pack, 16 hours smoke): Slightly sweet but denser, fruity smoke flavour.
