This I had to see for myself.
You know what? It works! It is probably not the most efficient way to cook corn if you are cooking more than a couple ears. In that case it’s faster and easier to steam or boil. But since I’m often cooking for one, and I have the patience of a hummingbird, I like the idea of quickly cooking one ear of corn in the microwave.
I can also verify that this works, and it's really cool. The corn comes out of the husk warm and completely clean.
