Though our recipe calls for this corn to be baked in the oven, it would also be good cooked on the grill.
Combine butter, cilantro, lime juice and zest, cayenne, salt, and pepper.
Heat oven to 450 degrees. Leave husks on, but pull off any loose silk or dried husk. Roast 6 to 10 minutes, turn, and roast 6 to 10 minutes more, or until tender when pierced with a knife. Serve with cilantro-lime butter.
