Remove stem, visible silk and peel corn until only a couple layers of husk remain. The corn should be visible through the husk.
Mix all the ingredients except the lime and corn in a bowl.
Grill corn over medium high heat until all sides are dark and almost black. Remove from the grill. Once cool enough to handle, peel the husk and brush off the silk. Return to the grill to reheat if needed. Coat corn with dressing and serve with lime.
