Freezing sweet corn is easy to do and the best way, in my opinion, to preserve it. There are many who can it in jars but the cooking method for that I think takes away from the freshness. My mom shucks and removes the silks from hers and freezes them on the cob. I don't have space to do that so I remove mine from the cob to freeze. This is my method. There are some who add extra ingredients to their corn, like sugar, but if your corn is sweet it doesn't need it.
