Keij's BBQ smoking chips are completely natural and suitable for both charcoal and gas barbecues. The wood has been carefully selected to ensure the highest quality. Cherry wood gives a fruity, sweet smoky flavor that goes perfectly with beef and game. Sprinkle a handful of wood chips on and around the hot coals. For a more intense smoky flavor, you can pre-soak the chips briefly in water. The use of a smoker box is essential on a gas barbecue. A smoker box is also more practical for longer smoking processes.
