This instructable will show you how to make your own charcoal for grilling out or using in a smoker. In essence, what you are trying to do is take standard hardwood and taking the wood gas out of it which will cause the wood to burn more slowly and at more of a smolder. The wood gas is the part of the wood that makes it flammable so once this is removed, you have your charcoal.
This homemade charcoal will not burn as long as standard store bought charcoal. This is due to all of the additives they put in them at the factory. The homemade charcoal will burn cleaner and is more "green" than store bought charcoal. One batch will make quite a bit of charcoal. The wood will burn up some and reduce the amount you have, but it won't reduce a whole lot.
You use this just like you would regular store bought charcoal. Lighter fluid or charcoal chimney will get it started. I make my pieces larger because I typically use it for smoking rather than just on the grill. You can make the pieces as large or as small as you want.
Are you ready? Lets get started!
