Maple Wood Chips are also great for poultry, pork, salmon, arctic char and trout. To use the Maple Wood Chips, soak them in water for at least 30 minutes before you are ready to smoke. When they have been sufficiently soaked, remove the Maple Wood Chips from the liquid and place them into a Napoleon Smoker Pipe, and place that pipe directly on the sear plates of your gas grill.
