Unblanched Whole Cobs - the easiest and quickest method: -Shuck, add to freezer bags, extract air, and toss in the freezer. (See Note* for cooking method.)
Uncooked Corn Kernels - the second easiest method, since you don't need to cook the corn first:-Shuck and cut the kernels off the cob into a large bowl.-Spoon kernels into freezer baggies (or containers), remove as much air as possible (I use my handy straw), seal and freeze.
Blanched or Cooked Corn Kernels - This third way is the most traditional way to freeze fresh corn:-Bring a large pot of water to boil.-Drop shucked ears into boiling water and cook 2-3 minutes.-Remove from water to a large bowl and let cool a few minutes until you can handle them.-Cut kernels off of cobs, spoon into freezer baggies, remove as much air as possible (again using a straw), seal and freeze.
