Dig out a pit or build a morter pit where you can place the kettle. A brick and morter pit is usually the best type of pit to build and it will last for a long time.

Place the inner barrel, the one with a portion made to act as a drawer, inside of the larger barrel and place it in the pit.

Attach the larger barrel above the heat source, shielding the inner barrel, to roast the peanuts in the bottom of the inner barrel. The heat source can be an open pit fire or an electric burner. Most people use electric burners plugged into an electrical outlet simply because they are safer. There are several types of electric burners, such as a portable ones that are usually used outside. There are also permanent electric burners that are used indoors and are simply plugged into an electric outlet.

Add old peanut shells, corn husks, or sawdust for the heating source in the pit. You do not need to use gas or kerosene. This is also a great way to use low cost fuel.
