I'm a dehydrator-geek, but I find that chicken, ham, cubes of cooked sirloin are quite hard to rehydrate (bison burger works well though). So I've turned to FD for my chicken and beef. Mountain House makes good stuff, and I buy in bulk (#10 tins--the size of a big coffee tin) from a place called The Epicenter (theepicenter.com). I portion it out into 1.0 oz units and vacuum seal them. They will last at least a year if kept in the freezer. Each 1 oz. portion will rehydrate to a 3.0 oz serving. For a multi-day trip, I'll open 2-3 vacuum-sealed portions and transfer them to a quart freezer zip lock, and carry it that way. It won't spoil, and I can use only what I want for each meal. As mentioned, these meats have virtually no fat in them, so it's good to add a bit of oil ("hog fat?" whale blubber?) to the soup/stew/ramen/rice (though not necessary). The FD meats ARE a bit salty, which is used as a preservative. I also like MH's FD peas, corn, and beans. With veggies, meat, bouillon, and quick rice/pasta, you can score a fast and tasty freezer bag dinner.
I found a can of turkey Spam in the pantry this morning, and I'm taking advantage of a cold, dry day to see how that dehydrates. I'm pretty sure it will be stupid, but what the heck. Laurie, Sarah, and Dicentra, I know you're laughing at the Spam thing right now. But when you have a dehydrator, you're unstoppable... (I can always feed it to the racoons).
