Smoking chunks are pieces of hardwood typically under two inches in length and are an ideal choice for producing smoke over long periods. Smoking chunks create more smoke and do so for longer, meaning you won’t have to add more wood every half-hour. Many people who smoke their food use a smoker, which is a piece of equipment that cooks food in a controlled environment at lower temperatures. Smokers come in many forms and sizes, ranging from tiny electric units to large smoker rigs.
