Husk the corn.
Cut the corn from the cob by holding the ear in a 9x13 pan and cut the kernels from the cob using a sharp knife. The 9x13 pan helps reduce the mess.
Put 9 cups of corn into a Dutch oven pan.
Add the water and salt.
The sugar is optional. If your corn is very sweet it is not needed, but if you would like it to be a little bit sweeter add the sugar. You can adjust the amount of sugar to your tastes and to the level of sweetness of the corn.
Cook over medium heat until the corn turns a deep yellow color, and it is hot. This will be about 15-20 minutes.
Remove from the heat and allow it to cool.
Once cooled, measure the corn and put it into a resealable bag. Burp out the excess air and seal. Lay flat in the freezer to freeze. I figure on ½ cup of corn per serving.
This keeps frozen for up to 1½ years.
