Some of today’s gas barbecues come equipped with a metal smoker box that sits on top of a dedicated burner. Just turn on the burner and add as many damp wood chips as you like. You can control how quickly they smoke by turning the knob of the burner higher or lower. Some of the boxes have a separate compartment for water, which will provide a steaming effect on the food, too.
If your gas barbecue doesn’t have a dedicated smoker box, you can purchase a heavy-gauge stainless steel smoker box to sit right on top of your cooking grill. The metal will conduct the heat of your barbecue to the soaked wood chips you pile inside the box. The holes in the lid will direct the fragrant smoke over your food. When the wood chips have burned out, you can simply open the lid and add more, if you like.
