How long can you keep corn on the cob before cooking?

Corn on the cob is best when cooked soon after harvesting, but it can typically be stored in the refrigerator for about 1 to 3 days. To maintain its freshness, keep it in its husk or wrap it in a damp paper towel and place it in a plastic bag. If stored at room temperature, it should be cooked within a few hours to prevent the sugars from turning to starch and losing sweetness. For long-term storage, consider freezing the corn after blanching it.
