Biltong biltong was made during the cold winters of the South African Highveld for best results. The cold, dry air typically dried out the biltong much more effectively, and in the best possible food safety environment. Mould and bacterial risk are at a natural minimum, and thicker biltong cuts can be hung to dry slowly for a richer texture, fuller flavor and dark colour. Heat has only been introduced into the process in recent years, and traditional biltong makers maintain that heat makes for an inferior end result. Due to increased risk of bacterial and fungal growth, the heated method, such

Other recipes, which were handed down from generation to generation, require the biltong to be left overnight in the vinegar, salt, and spice solution (between 12 and 24 hours). The spice mix traditionally consists of equal amounts of rock salt, whole coriander (slightly roasted), roughly ground black pepper, and brown sugar.
