The biltong boxes are made in a private carpentry workshop, using only the best materials. The outer shell is made from a tropical plywood called "Lauan/Meranti." Oak runners are used as the framing and legs. This provides excellent strength and rigidity to the little system. A removable catchment plate is installed with gauze covering at the bottom of the system. This allows maximum air flow and keeps out any bugs or flies. Similarly there is gauze covering the breather holes made in the side of each box. There is a light bulb installed underneath this catchment plate, which, when plugged in provides the airflow necessary for the biltong to dry. A little lid capped with a brass knob finishes off the system. You also get Pete's tried and tested recipe for making biltong.
