Biltong is a dried, salted and spiced beef that, cut in wafer thin slices, is a tasty snack, or a nice addition to a salad. It is also a useful way of preserving meat without refrigeration and thicker slices can be soaked for 24 hours and made into a casserole or stew.
I was shown how to make it years ago during a visit to South Africa. There, it is traditionally made from venison and ostrich, as well as beef.
Biltong should not be confused with jerky, which is thinly sliced beef that is dried in the sun to a stiff, board-like consistency. It should retain some flexibility to enable slicing.

After the trimming, a solid slab of fat-free young beef
My choice is a muscle from the silverside of a heifer that can be
trimmed out to remove every vestige of fat and that shiny sheath that surrounds each muscle. It takes a little while but the effort is worth it, and the trimmings are not wasted. They make an excellent stew with carrots and onions and some mixed herbs.
My favourite source is the butcher at Waipawa, a small Hawkes Bay town between Waipukurau and Hastings. While they no longer kill their meat on the farm each week, they still make their own smallgoods and the shop produced a champion sausage some years ago in a national competition. They still make real saveloys that bring back childhood memories of the days when butchers’ shops had sawdust on the floor and a big wooden chopping block surrounded by carcases and joints hanging on great hooks from iron rails. The housewife engaged in banter with the butcher while her order was wrapped up in brown paper and tied with string, and the final flourish was the cutting of the string above the knot with the point of the knife that then went back into the scabbard at the butcher’s waist.

Kay's grandmother's scales
There was a wonderful smell that was a blend of sawdust, manuka smoke and mutton fat. There were no plastic wrapped, expiry date stamped trays of meanly sliced meats. Each enamel tray was piled with thickly cut chops and cutlets, and the centre of attraction was a large corner rib, or a tightly rolled roast. A pile of honeycomb tripe, livers, tongues, kidneys and brains completed the display
For the small child in a push chair there was another delight. A cold saveloy(in those days they were safe to eat without cooking) was cut off the big bundle beside the sausages hanging from the rail above the counter and presented to the youngster. It could be gnawed on happily for the next half hour.
The Waipawa shop is an honest reminder of those days when meat was plentiful, reasonably priced and dietary fads were of little interest to those who worked hard for their living and enjoyed each meal. I enjoy calling in there each time we take a load up to Napier for the ship.
But I digress. It is not much use going into a supermarket and asking if they have an uncut heifer silverside, and then expect to obtain a part that is cut lengthwise. Waipawa is another matter.Even with the best co-operation and a careful selection, there is still a fair amount of trim (hence my comments above about making a casserole). Kay and I use an old set of scales in the kitchen and it is a good mental exercise to have to convert the old Imperial pounds and ounces to kilograms and grams.

The brown sugar and spices are massaged into the meat

Covered with salt
From the 2.2 kg of silverside I trimmed 540 grams of fat and unattached muscle to end up with a fat-free 1.66 kg of meat in a single piece. Then I massaged it until it had totally absorbed 160 grams of brown sugar and about 40 grams of allspice, mace and powdered cloves, plus a good dash of black pepper. It is surprising how the meat takes in the sugar and the spice and it is several hours before one sees any liquid in the bottom of the bowl. The ability of the meat to take the sugar and then the salt is very much determined by its freshness, and I wouldn’t try making biltong with beef that had been aged and had dried at all.

A pretty pickle as the salt takes hold
Held overnight in the refrigerator it was ready next morning for the salt, and I poured 500 grams of plain non-iodised salt over the meat and put it away again. Another half day and the salt begins to melt in the juices that are being extracted. A turning in the morning and again in the evening spreads the salt and shifts the area of meat that is immersed.
It should take about three and a-half days for the weight of the meat to be reduced by about 15 per cent. (This is determined by the thickness of the piece of meat and on this occasion it took four days.) It can then be taken from the heavy brine and hung on a string in a shady place with a good draught of air.

Hung under the carport where there is a good drying draught out of the sun
The carport is ideal, providing it is not close to the street. A couple of years ago I had a nice biltong just about ready to take down when it disappeared. I suspect a passerby, but I doubt whether whoever it was found it to their liking, particularly if they tried to put it on the barbecue.
It will probably take a couple of weeks to dry properly and lose another sixth of its original weight, bearing in mind it has also taken up salt into the tissues. In that time it will probably sweat overnight and the beads of moisture can attract flies. These can be discouraged easily by dusting the biltong with cracked black pepper.
Finally, a sharp knife and the wafers are cut across the grain. The salty, spicy, chewy meatiness has its own attraction. If I was in Auckland someone would probably ask to recommend a suitable wine. For me, biltong goes well with good friends and good conversation.

The finished product: all it needs now is a piece of bread and a beer
Daily weight loss (over days 5 to 8 we have had high humidity and rain, so the loss should have been greater:
Day 1 1.66kg
Day4 1.44kg
Day6 1.32kg
Day8 1.24kg
Day11 1.1kg
However, on day 12 the job was complete and a first few slivers were taken for a testing. Spot on, not too salty, and still with a good even level of density that makes for even slicing. In a month or so, that won’t be so easy and it will have dried out some more. Wrapping in paper will slow the further moisture loss, without the risk of sweating. There is no need to refrigerate.
