Trail Food Dehydration Resources
I've only really gotten into dehydration recently but I am really amazed at the potential of it. For longer trips that require weight conscious ingredients, or if you want to save money - D.I.Y dehydration is an awesome hobby to pick up if you are serious about backpacking or your food for it.
There are alot of free resources out there on the web to sift through for doing your own Drying/Dehydration at home, but I found some that I really liked and thought were useful to people just wanting to start up in it:
Dehydrating Food - Backpacker Chef
Trail Cooking.com - Dehydration 101
Choosing the right Dehydrator
Alton Brown - D.I.Y Food Dryer
D.I.Y Solar Dehydrator
