By contrast, biltong is typically made from fattier cuts of beef or other animal meats cut into slabs or large pieces and marinated with spices and vinegar to prevent microorganisms from growing. They are then air-dried without the use of heat, and after a week or so, they're usually cut into slices that are thinner than your average jerky, resulting in a crumbly, flaky mouthfeel, sometimes compared to charcuterie.
