Believe it or not, you can actually freeze whole ears of corn to have fresh corn on the cob As a treat or later when fresh corn is no longer available. To freeze corn you want to make sure you’re using ears of corn that has been picked as recently as possible. The longer it is been picked, the starchy or the corn will get. If you have the opportunity to pick corn fresh from a farm that is the best way to do it.
In order to freeze whole ears of corn, first you want to remove the green outer leaves as well as the silk and the stem. Then blanch the corn 4 to 6 minutes in boiling water.
Allow the corn to cool and then place each ear in a vacuum-sealed bag or a Ziploc freezer bag. Place the open bags in the freezer. Once they are completely frozen, then vacuum seal the bag or seal a regular Ziploc bag once you squeeze all the air out. You can freeze these ears of corn for up to a year.
In order to thaw the ears of corn, they will take about 2 hours to thaw at room temperature, or you can put them in the refrigerator the night before to thaw. You simply cook as you would an ear of fresh corn on the cob. Simply put the ears of corn in a pot of water and bring it up to a boil, then put a lid on and reduce the temperature to a simmer for about 5 to 10 minutes.
