Drop corn into boiling water.
Boil for 4 to 6 minutes.
Plunge corn into ice bath, using one tray of ice per ear of corn into the bowl.
Using a sharp knife, remove corn from the cob.
Pack the corn into freezer-safe containers—be sure to label and date each container so you know what it is and when it's from.
Tuck the containers of corn into your freezer and wait. On a cold day in winter you'll thank yourself for taking the time to blanch and freeze your corn. Enjoy.
