pemakin: This seems to be what a lot of the old trappers & mountain men used to take with them. It's made of dried beef with spices (60%) and rendered beef fat i.e tallow (40%). You then dry it on a low heat in the oven. I was watching a Ron Hood DVD (Cave cooking series) where his wife made some. it's really high in calories and comes out like jerky. You just add some water & heat to make a nice stew. Worth a look.
