These BRADLEY FLAVOR BISQUETTES are rendered from the finest hardwoods - made to exacting standards using controlled pressures. They feed automatically through the Bradley Smoke Generator to create clean, slow, low temperature smoke for up to 8 hours safely. The BRADLEY FLAVOR BISQUETTES will not burst into flames and will provide their own distinctive aroma and wonderful flavor to smoked foods. Certain types of wood give a better flavor with different food groups. There is no hard and set rule to this, however, try using hickory or mesquite with pork, beef or red game meat. All types of seafood are excellent with alder, or maple. Fruit woods work very well with poultry and fresh water fish. Try using cherry with wild duck or chicken.
