One of the few advantages of the lockdown has been that many outstanding projects have finally been completed. One of these was to build a permanent drying box to make biltong. Biltong is tasty dried and cured meat that originated as trail food in South Africa at a time when cold storage was not available to preserve it. Vinegar had already been used since the 16th century in the curing process, and the use of spices such as pepper and coriander to combat bacteria has also been long understood. Combined, they enabled the early Boer voortrekkers to produce stocks of dried food to take with them as they journeyed into the interior of southern Africa.
You can make biltong from just about any meat, but it does need to be better quality cuts such as sirloin, fillet or rump; the name, derived from the Dutch bil (rump) and tong (strip), reflects this.
Originally biltong might have been dried hanging from a bush in the open air or from the rafters of a settler’s home. Direct heat is not used, and the secret is ensuring a constant passage of dry air around the meat throughout the slow drying process. It should not be confused with jerky, which is made from thinner strips of meat, preserved in an entirely different manner and often smoked (biltong never is). The taste is very different, and many people consider biltong vastly superior.
The makings of a permanent drying box for biltong
British weather is far removed from that of the African veldt and seldom offers a warm, dry breeze, so some form of box is needed to create the right conditions. I’ve used cardboard boxes in the past but an old wine crate measuring 20in x 13in x 9in formed the basis for this one (ideally I would have preferred something larger, but being confined to barracks meant that it wasn’t possible to go out looking). As the light lid had warped a little, adding a frame extended the dimensions slightly while strengthening it. Treated wood, which might release tainting fumes when warmed up, should be avoided. I fitted three hanging bars using threaded rod left over from another project, but dowelling or similar would have been fine.
The top was drilled for a small computer fan as an extractor, while a light bulb at the bottom provided gentle warmth. The fan is not essential as heat from the light bulb alone creates air movement, but LED bulbs are not suitable. It should be very low wattage as you don’t want to produce too much heat; 40w is more than enough. Holes at the bottom on the front and sides provide air inlets but need to be covered with mesh to keep insects out. If you are not adding a fan you’ll need more holes in the top to allow the warm air to flow outwards. The viewing window isn’t strictly necessary, but I had an old photo frame glass handy and it’s always nice to see how things are going at a glance.

For the first batch I raided the freezer for a 2lb boned muntjac haunch, though any venison makes first-class biltong and larger species allow longer meat strips. If you are using beef you can leave any fat on, as this is itself delicious once dried, otherwise remove it. The box would have accommodated twice this amount in longer strips, or by using longer pieces of hanging wire to make full use of the space available.
It took just three days for the first batch to dry properly, during which time it reduced to well under half the starting weight. This is one of the reasons that commercially produced biltong is so expensive. All that remained was to vacuum pack the finished biltong, though I needn’t really have bothered – in our house it never lasts long enough to go off.
Biltong can be made from just about any meat and is a tasty savoury snack
There are many recipes to make biltong: this is a simple one which produces great results. Quantities can be adjusted according to the amount of meat used, and you can experiment by adding paprika, chilli flakes, dried garlic or other ingredients to your taste.
