I use jars like that for storing rice, popcorn, pasta, salt, etc.
a ‘just in case the power goes down’ idea is to buy frozen mixed veggies, thaw and cook in large jars (I use the five bean salad jars from Sam’s Club), reusing the lids tonged from noiling water to top the bubbling veggie mix. I have yet to have even one of the jars yield that familiar ‘pop’ when cooling. Only able to do three jars at a time, but it works.
