As a kid, I’d hoard Halloween candy and eat it one bit at a time over the course of months. My parents never threw it out, and I’d typically still have some of last year’s candy when the next Halloween came round. Chocolate never goes bad, in the sense that it is dangerous to eat it— it just separates out which might not taste as good, but if you don’t mind that, it’s fine to keep around. I was fine with it. And of course, my favorites were always the hard candies and other sugar based ones, not the chocolate anyway.
