Jerky is a food that dates right back as far as ancient Egypt. In America in the heyday of the Wild West, cowboys would cut strips of meat from any animal that was too big to eat all at once, such as bear, buffalo, or whale, and hang them up to dry in the sun.he word Jerky comes from the Spanish word for jerked meat charqui. English speaking people heard this word and changed it to a word that was easier for them to pronounce jerky. Jerky is a nutrient-dense meat that has been made lightweight by drying.
