I have heard that you can just cut the corn off and freeze, no blanch. So I'm trying that this yr. I have cut the corn off the cob then blanched before freezing (to save time and space when blanching and I've blanched whole cobs then cut the corn off. Not much difference between whole and cut off then blanching. But I was talking to an experienced corn freezer and was told I didn't need to blanch. Have you tried all three methods? Which do you like best?
