Sweet summer corn is the best. You can make variations of the cilantro butter with different herbs and use lemon juice. If the corn isn't too sweet, add a little bit of maple syrup to the butter.
Ingredients
8 tablespoons (1 stick) unsalted butter, softened
1 tablespoon freshly squeezed lime juice
1/2 teaspoon lime zest
1/2 teaspoon sugar
1/2 teaspoon salt
1/4 cup chopped fresh cilantro
12 ears fresh corn, shucked
Directions
1. Combine the butter, lime juice, lime zest, sugar, salt, and cilantro in a medium bowl and mix well.
2. Grill the corn on a medium-hot grill for 10 minutes, turning occasionally.
3. Transfer the lime-cilantro butter to a serving bowl and serve with the corn.
