Corn starts losing its sweetness once it's picked, so it's best to eat it fresh. But America's Test Kitchen has a way to store it for up to six months.
The video describes the process: shuck the corn and put it in boiling water. This deactivates the enzymes that convert sugar to starch. Once it's boiled, remove the corn and put it into an ice water bath. Once cooled, dry on a dish towel and place in an air-tight bag. It will last in the freezer for up to six months.
Once you're done eating, don't throw out those cobs just yet. They are perfect to roast juicier chicken.
