And salt.
Salt is essential for survival and I think many people over look it in prepping.
It’ll store excellently in canning jars as they are hermetically sealed and there’s no moisture in or out to make it cake and of course, it doesn’t spoil.
I keep a few of the pourable small containers. They’re at least cheap. Yep, it’s a must-have.
Salt is literally a rock. Even caked up, just take a hammer to it.
