Question: how much jerky does 1 kg of beef make?
Answer: It depends on how moist you like your jerky. A typical jerky loses half of its starting weight in moisture, so 2:1 is the proper ratio. "Low moisture" jerky can actually be 1/3 the starting weight, a 3:1 ratio. So 2-3 pounds of beef will make 1 pound of jerky.
