Corn has a ridiculously short season. Tempting though it may be to purchase a whole basket full of sweet corn from the farmer's stand, you know you won't eat it all before the sweet begins to fade. It is quite a fun production to remove the kernels and freeze them (though they do fit into your freezer better that way) and you may not have time to do that. So, just freeze a few whole ears for a time when you only dream of summer. The nutrition facts for one ear of unbuttered corn were designed at Calorie Count.
as many ears of corn as you have room for in your freezer
Rinse the ears. Pull back the husks but do not remove. Pull off all the silks as best you can. Recover the cob with the husks, give a twist at the top to seal.
Pop into a freezer bag, remove as much air as you can, and place in the freezer.
Boil, grill, or microwave frozen or thawed ears. If frozen allow more time.
