Pemmican
I'm every bit the nutrient-rich, slightly fatty, humble, suet-like cake of my native American ancestors. I am not for everyone and definitely not designed for every day consumption. I'm a little too substantial for that.
While I can admittedly be somewhat dense and boring (especially to more refined palates), I can also save your life when things go wrong. I have the ability to encourage, sustain, and bridge you over to better times. I am dependable that way.
Unfortunately, I'm not something you'd probably ever look forward to having. Not when there is an entire world of fancy, laboratory-derived, “power” bar type snacks in shiny packages available. However, will you ever be glad to find simple me at the bottom of your daypack in a survival situation.
Take me along. I make a decent companion for life's journey.
