Here's how we cook corn on the cob: After removing the most loose outer husk, we soak the ears in cold water for an hour or so with husks on and silk still present, then toss them on the grill, turning regularly for roughtly 15 minutes.
They steam and char a little. Some of the husk will char a bit, and most of the silk will burn off. That's good.
Peel and eat. For me, no butter, no salt on it. Tastes good the cave man way.
