See previous post about keeping the temperature stable...
I was also having problems keeping the smoke going steadily. I was using beech chips, which were roughly 5 mm square by 2 mm thick. Tried first using a steel smoker box with a small handful of wetted chips. The box was placed on the hot charcoal and smoked vigorously for maybe fifteen minutes before apparently burning out. I then tried some wetted chips wrapped in aluminum foil, much the same experience. What's the secret of keeping the smoke going steadily for a longer period? Put it to the side of the charcoal? More chips?
