If so, is there any preventative measures I can take to prevent candy from expiring?
I'm curious because Halloween candy after two years tends to look a little...off, and I'm not sure if it's safe to give it back out this Halloween. Since there's no noticeable expiration date on candy packages, is it safe to assume that they don't expire?
Same goes for homemade candy, does it expire too?
I want to know for the majority of chocolate-based candies, rock-sugar candy (jolly ranchers, etc) whether or not they expire
