I really love popcorn and usually pop it on the stove and eat it right away. However I'd like to make it ahead to save for snacks at work. I tried this once before and the kernels got a bit stale tasting, not very crisp. Are there any techniques for making popcorn that can hold up for a day or two, and how long would it last?
Unless you coat the popcorn (with caramel, etc), I know of no way, other than SAJ's vacuuming idea, which is quite a good one, imo.
