Landjaeger sausage, I have it made up out of venison, and like to have a couple in my pack at all times. I have kept the same landjaeger in my pack for weeks at a time, it lasts for a long time, I dont remember it ever going bad, super high energy and next to Pemmican, incredible stuff.

I dont make it myself, although you can easy enough...you gotta have a good set of chompers.
