The method works well.
But I still prefer to shuck and steam or boil fresh corn.
Call me old fashioned or stubborn but it's the way I prefer and any silk left after shucking comes off easily. Any silk on the ear should be seen as natures dental floss.
For me the most important aspect is that the corn be fresh picked so that it's consumed before the sugars degrade into starch.
I set a 12 hour limit from harvest to pot but you have to trust your vendor. So far the road side stands around here haven't disappointed me in there honesty.
