To freeze corn on the cob, take off the husks, blanch the corn, and take the kernels off the cob after blanching to keep the corn from absorbing the flavor of the cob as it freezes. Store the corn in an airtight package to maximize its shelf life.
- Prepare the corn for freezing
Remove the husks from the corn, and get the silks off as well. Cut out any blemishes from the corn, and get rid of any insects or worms.
- Blanch the corn
Fill a large pot with water, and bring the water to a rolling boil. Wash the corn cobs thoroughly beneath running cold water, and then set them into the boiling water. Leave the burner on high, and remove the cobs after seven minutes if their diameters are 1 1/4 inches or less. Add two minutes for ears between 1 1/4 and 1 1/2 inches across, and four minutes for ears bigger than 1 1/2 inches across.
- Take the kernels off the cobs
Cut the kernels from the cobs, and put the corn into the desired storage bags. Leave a 1/2-inch clearance at the top of hard freezer containers, but fill plastic storage bags all the way, leaving as little air as possible.
