When stored in a sealed glass jar in a cool cupboard, unpopped popcorn can maintain its freshness for months. For longer storage, store popcorn in the freezer, it will last for a year or more. Popcorn should pop within 80 to 90 seconds, if it takes longer, it probably has dried out. To add moisture to popcorn, add a teaspoon of water to your jar of popcorn (1 teaspoon per 1 quart of popcorn) and seal the jar for two days. Open the jar and shake the popcorn at least twice each day. Then try popping some of the corn, if it has regained its moisture it should pop more quickly. You can also leave it open in the refrigerator for a day or two, then seal it up. It will absorb moisture from the refrigerator.
