CORN & CUCUMBERS
Try to use corn as soon as possible after purchase; but if you can't, it should keep for 1 or 2 days in the refrigerator.
If you like corn off the cob, you can slice the uncooked kernels off the ear and freeze them in an airtight container for up to 6 months. This is a great way to stretch the taste of summer far into the fall.
Refrigerating cucumbers extends their life for about a week, especially if you store them unwashed and loosely wrapped in a plastic bag. If possible, try to use them right away it's the bursting juiciness of crisp cukes that makes them so special.
