In addition to the taste, smoking meat is a great way to preserve food off the grid. You can smoke all sorts of meat, and even use your smoker for making dried fish or pemmican.
Remember, when smoking something you want to avoid cooking with direct heat. Instead, pile the coals up under one side of your cooking grate, opposite the side with your meat.
You can buy different sized wood chunks, depending on what your smoker will accommodate. The larger chunks will burn and create smoke longer, reducing how often you need to replenish them.
