Place one piece of foil in a diamond shape. Place the corn in the middle. Place 1 tablespoon of the unsalted butter on top of the corn, and add a pinch of salt and cracked pepper. Tightly roll up the corn like a tortilla, making sure to wrap the sides well so the butter doesn't leak out when grilling.
Heat your indoor grill pan or outdoor grill until it's really hot! Add the wrapped corn and turn every 2 minutes for 20 minutes. Remove from the grill and let stand for 5 minutes. Remove the corn from the foil and serve immediately. Watch Cristina make this recipe!
