One thing I rarely see mentioned but is critical is salt.
It’s critical for survival and not a lot of places are near a good supply of it.
I wash out my glass spaghetti sauce jars and use those to store it so it doesn’t cake up. Since the lids have that built in gasket, it’s hermetically sealed and keeps the moisture out.
And they seem pretty corrosion resistant.
I would also to a decent supply of high quality vitamins, to avoid vitamin deficiencies.
I remember my parents and grandparents having rice in their salt shakers so it did not cake. My wife’s family used saltine crackers in the same way. Wouldn’t recommend the crackers now because they did something to them making them get rancid after a while.
