>pasta sauce
Better to have canned tomato paste, olive oil, dried herbs, salt. All last indefinitely and make a good enough pasta sauce. Cans outlast jars as a general rule.
Anon has canned tuna that doesn't "expire" until well into 2028…
>Canned fruit may be an option but remember that vitamin C is lost by heating in the canning process.
Get powdered C for C needs.
Canned fruit is for morale.
It is anon's experience that products in jars spoil before those in cans. In a survival situation, a little chemical contamination from can linings is not of primary concern.
One of my creations. Too bad it didn't turn out to be true.
My strategy for surviving a dark winter of hyperinflation and food lines and "food assistance" (only in return for getting jabbed) is a diet high in proteins and fats, very low in carbs. Where I live, proteins come primarily in cans, not jars.
