I husk it, soak it and grill it until it's toasted, almost crunchy. Do keep an eye on it, from toasty to charred it's just about a heartbeat. I've been meaning to try doing this in the rotisserie (sp?), but so far I turn them by hand. Tongues damage the corn, so wear a fresh pair of gardening gloves to rotate them, and do it quickly. My wifes puts salted butter on them, and that's good, but I prefer them naked.
Long time ago we used to bury them and then make a fire over them and let it burn for a half hour, maybe forty minutes and dig them out. It's like steamed, but much firmer and not quite as "wet". Sprinkle a bit of sea salt on them if it fancies you, but again I prefer them without. Incidentally, you can do the same with potatoes. Sweet potatoes are best tossed into the fire and let to char on the outside, but that's another thread.
