Frozen corn lasts for six to eight months in the freezer, but the ears of corn must be blanched and dried to keep them from becoming mushy when cooked. Blanching before freezing stops the enzymatic action that can destroy the nutrients and flavor of your corn. Freeze your corn as soon as possible after harvesting to prevent the natural sugars from turning into starch, a major contributor to flavor loss in corn.

Step 1

Harvest your corn early in the morning for the best flavor and texture. Peel the corn husk back and push your fingernail into a corn kernel; the kernel should produce a milky liquid. This step isn't applicable if you purchase your corn from a produce stand or farmer's market.

Step 2

Peel the husks from the ears of corn, removing as much of the silk as possible. Scrub the ears of corn lightly with a vegetable brush to remove any remaining silk threads.

Step 3

Wash any dirt and debris from the ears of corn under cold running water. Place the ears of corn on a cutting board. Trim the remaining stalk stubs from the bottoms of the ears with a kitchen knife.

Step 4

Fill a large pot about three-quarters full with water. Place the pot onto the stove top over high heat. Allow the water to come to a rolling boil.

Step 5

Fill an additional large pot or your clean kitchen sink with ice water. Use about 12 cubes of ice per ear of corn.

Step 6

Lower four or five ears of corn into the boiling water with tongs. Allow the water to return to a full rolling boil. Cover with a tight-fitting lid.

Step 7

Blanch the ears of corn in boiling water; the National Center for Home Preservation advises blanching for approximately 7 minutes for ears that are up to 1-1/4 inches in diameter, between 7 and 9 minutes for ears that are between 1-1/4 and 1-1/2 inches in diameter and 9 to 11 minutes for ears larger than 1-1/2 inches in diameter. Pull the ears of corn from the boiling water with tongs after the proper blanching time has been met.

Step 8

Plunge the hot ears of corn directly into the ice water immediately after blanching. Allow the ears of corn to cool for the same amount of time used to blanch them.

Step 9

Dry each ear of corn completely with paper towels before freezing. This reduces the amount of ice crystal formation on the corn while freezing, which helps prevent the corn from becoming mushy.

Step 10

Wrap each individual ear of corn in plastic wrap. If steam develops inside the plastic wrap, the corn is not completely cooled and must be unwrapped and cooled completely before rewrapping and freezing; any steam trapped inside the plastic wrap will cause ice crystal formation, which will lead to mushy corn.

Step 11

Slide the individually wrapped ears of corn into plastic freezer storage bags or containers. Remove as much air as possible from the packages before sealing. The individual plastic wrapping and freezer containers provide extra moisture-vapor protection to keep the corn as fresh as possible.

Step 12

Label the bags or containers with the date of storage and place them in the freezer.
