Taste the ADVENTURE Our Rosemary Truffle Biltong starts as hand-cut strips of the finest American beef. We then marinate each strip in our time-tested blend of vinegar, salt, black pepper, coriander, rosemary, and black truffle. During the air-drying process, each cut of beef develops an extraordinary depth of flavor. The result: a unique cross between jerky, slow-roasted beef and fine Italian prosciutto.
