I have some peanut butter that I stashed as a test in 2016, opened it last week - still good. Have one more that I’ll save till next year. When the grand kids lived closer we used a jar per month. Now not so much, but I used to have a couple of jars and some crackers in my car during the winter when I was commuting 150 miles daily-for emergency purposes.
5 years?!?! Now that’s excellent intel!
