This process is so simple. Simply shuck all the cobs of corn that you want to freeze. Then cut all the kernels off the cobs. I like to stand each ear on its end in a large bowl to catch the kernels as they start coming off, and use a small sharp knife to slowly and carefully cut the whole length of the cob. Then I turn and do another row until the cob is clean.
When finished cutting off the corn, simply place it all in a large ziplock freezer bag, squeeze out the air and seal.
When ready to use, squish the bag around on the counter to loosen the kernels and measure out what you need for your recipe.
