It is a common problem for the Bradley Smoke Generator to burn and In addition, if no more bisquettes are fed through at the end of a smoking cycle, the last bisquette can smolder into ash on the heating plate unless they are manually removed! What a huge waist! This can cause a very charred tasted to impart on the meat if it is not removed within the 20 minute smoke time for the bisquette. By using the aluminum bisquette savers, the last bisquette can be pushed off the heating tray preventing this from happening. In addition, by stacking a puck with every other bisquette, you can introduce a pulsed smoking cycle for a more controlled flavor.
