You'll want to post this on the Harvest forum here (linked at the top of this forum's page) as that is the forum with the food preservation, canning, freezing, etc. focus.

How to deal with corn is often discussed there and some of the regulars there say that freezing without blanching is best for flavor but it has limited storage time.

The approved guidelines call for blanching of course, especially if any long term storage is planned, but you might try it once without blanching and see if it helps your corn. Some say that steam blanching also works better than water blanching.

Personally we have found that it is the variety of the corn itself that makes the most difference as well as when it is picked. Corn left too long on the plant is going to be starchy in flavor no matter how you prep and store it.
