Corn on the cob Sour cream Mayo Chopped Cilantro Minced Garlic Cayenne pepper Cotija or Feta or Parmesan cheese Lime juice Start a grill running hot. While that heats up mix equal parts mayo and sour cream. Add in all other non corn ingredients to your tastes. I go cilantro > cheese > garlic > lime > cayenne. Throw shucked corn on the grill until it chars, rotating constantly. Slather that mixture on the charred corn and serve.
