Packed with calories that are much needed in a survival situation, pemmican is high on the "bang for your buck" food scale. It travels well, can be stored for a LONG time without refrigeration, & can be made with many variations so feel free to experiment with the extras that you add. Also, while not as high in fat and calories as the meat-fat version, vegetarians can make a similar product using peanut butter in place of animal fat and fruit or vegetable leather instead of meat jerky.
