Freshly-harvested corn is available all summer long since farmers plant crops at different times. It is best to eat fresh corn the same day you harvest or purchase it, however, that is not always possible. Fortunately, you can store corn in several ways. If you freeze your harvest, you can enjoy this year's corn until the next season's crop is ready for harvest again.
Store freshly-purchased or harvested corn in the refrigerator. Keep the corn in the husks and place them in the crisper drawer, if possible. Corn will keep for up to two days. Afterwards, it is still edible, but begins to lose its sweetness.
Freeze ears of corn. Remove the husks and boil the ears anywhere from three to eleven minutes, depending on your preference. Do not cook the corn longer than eleven minutes since the corn will cook some more when it is reheated. After cooking, drain, cool and place the ears in a freezer bag. Remove as much air as possible. Use within a year.
Freeze kernels of corn. Remove the husks and cook whole ears of corn in boiling water for about five minutes. Drain and allow the ears to cool. Use a knife and cut off the kernels. As a general rule, cut ¾ the depth of the kernels. Place the kernels in a freezer bag and remove all the air. Use within three months.
