The Cornish Biltong Company produces biltong from silverside of beef, with all excess fat removed, tenderised and washed with malt vinegar. The meat is rubbed well by hand, and spices are kneaded into it. The magic really happens when the meat is left to marinate in all the good stuff for up to 4 days. This allows the vinegar and spices to fully infuse the beef. After the marinating process, the meat is hung in drying cabinets until all the moisture has been removed, leaving a healthy, salt beef snack that tastes fantastic.
Both biltong and the spice mixes used in its production can be purchased on-line.
