Okay, no pemmican, so did you look at the bif bar recipes we posted a couple weeks back? Those are pretty bulletproof and darned good trail food.

As for pre-packaged, I packed Hooah bars in Iraq all the time in my EDC and BOB and never had a problem. They are pliable so even though they would disfigure from the handling, they were never gross. They seem to work well for a lot of people. I also packed a lot of those single serving peanut tubes that they sell two for a dollar at most stop and robs. Peanuts are good trail food, and tolerate a lot of abuse and have a pretty good shelf life. Corn nuts also seem to do well. I find that the extra salt is more desirable on the trail than sugar. They can pulverize a little easier than peanuts do, but generally are rugged enough for extended stowage.
Toasted soy nuts are also fairly rugged and high energy and reasonably palatable.
