I'll have to look when I'm home for the right ratios but pemmican is really straightforward

Pound, food process or otherwise pulverize jerky of choice into somewhere between granular and powder

Add some berries if you like 'em

Melt some tallow and then pour it over the powdered jerky. I use muffin tins since it makes it easier to be consistent.

I've noticed some people take some time to get used to it. I'll look up a more proper recipe with better instructions when I get home tonight
