Excerpt from Introduction.
Jerky is simply raw meat that has been slowly dried at low temperature. As the water is removed the meat loses both weight and volume. What it doesn't lose however is flavor. In fact the flavor of the meat is greatly concentrated which might explain why just about everybody with good teeth loves jerky.
These days jerky is popular as snack and it also comes in handy as a high-energy food for backpackers dogsledders trail walkers hunters fishermen boaters and other people who spend lots of time outdoors. For long-distance runners and sports competitors jerky can deliver a burst of energy all out of proportion to its compact size and light weight. For campers jerky is easy to pack and store. On an auto trip jerky is great for the kids and doesn't make a mess in the car and or course it's perfect for snacking during the football game or television shows - and for sneaking into movie theathers that don't allow their patrons to bring their own popcorn. Family dogs savor the stuff too if my Nosher is a good representative.
