When reading the synopsis of this book, it sounded perfect....but it ends up being a disappointment. Not much useable information about the dehydration process of different foods. It's made up more of recipes using the dehydrated items. I am doing a lot of dehydrating right now, and I've not found any help in this particular book on "how to", "how long", etc.However, if you are a jerky lover -- you might like this book. Lots of recipes and info about jerky.
