Only use wood chips approved for use with smokers. The majority of lumber today is treated with various chemicals that are effective at preserving the wood but are terrible to flavor a meal with.One classic way to use your infuser is to place your cooked items on a serving plate under a glass dish, cup, or bowl. Fill the underside of the glass with smoke and let it sit for about five minutes. Bring the plate to the table, remove the glass to release the smoke, and impress your dinner guests.
