When you think of buying an offset cigarette, you probably already know what it is and what you can do with it. In short, to avoid preaching in the choir, as it were, a smoker is a tool designed to cook food indiscriminately at low temperatures in a smoky environment. Smokers not only cook food but also give it a taste of the smoke produced by cooking fire. The smoker offset usually looks like a normal charcoal grill with 2 separate chambers, a cooking area and a second small firebox connected to one side. The shape of the firebox is what makes it a horizontal smoker.
