Some boil it, some “blanch” it, I keep it simple and use a tried and true method that I learned from my grandmother.
Shuck and silk the corn, wash it thoroughly to remove all the silks.
Place the corn in a Freezer Ziploc Bag. I use gallon size bags and place 5-6 ears of corn in each bag because that is what my family will eat in one sitting. I have friends that use quart size bags and only 2 ears, whichever you prefer.
Once all the ears are in bags, the fun begins! I take a straw and literally suck all of the air out of the bags to give it a vacuum seal affect.
Once sealed, I freeze. When I’m ready to eat, I place the ears in boiling water and boil for 20-30 minutes until done.
