Was thinking about this and was going to mention that I wouldn't bother actually creaming any of the corn, but I probably would probably cook all of it, maybe taking an ear or two out a little early to keep a good crunch factor. You might have to add a tablespoon or so of milk or other liquid.
Should mention that when I make it for the son it is vegan and no cheese! It's just that I make the mix and that is what I have in my pantry instead of the Jiffy boxes.
Some people expect the sweeter version without the diced chilies, if I do that I do a drizzle of honey to mark it as sweet.
It's funny regional variations, here in the Seattle area growing up and working it wasn't a common thing, but it always goes over well at potlucks and family gatherings and is now "my" dish to bring to such things.
