Fameal: A Long-Lasting Survival Food

While these kind of recipes are good for short term, I wouldn't make them with the intention of long term storage. The oils will almost certainly go rancid within 12 months (less, if your weather varies wildly, more if you can keep it in a freezer).

A good way to do it would be to keep the ingredients separately but not yet ground into meal. That way when the time comes you could grind it yourself and create the end product pretty quickly and easily. That being said you'd need a hand grinder if you don't have power but you COULD potentially get around that with a hefty mortar and pestle. Wouldn't want to have to do that OFTEN but needs must.

I bought a hand grinder a few years back as a back as my backup plan but I also have a grain grinding attachment for my Kitchen Aid and a Vitamix for when I have power. Thank goodness, because hand grinding is monotonous when there's other options lol.
