20. Popcorn Kernels
Not the microwave bags—just plain, dried popcorn kernels. When stored in a dry, airtight container, they can last almost indefinitely. They don’t spoil easily and stay fresh for years without refrigeration. You can pop them on the stove, in a popcorn machine, or even over a campfire. They’re a fun, easy snack and way more shelf-stable than you might think. Just keep them cool and dry, and they’ll be good to go whenever movie night strikes. Popcorn is definitely one of the foods with long shelf life you need in your pantry.
