How to Make It
Cook butter and, if using, bacon drippings in a medium-size cast-iron skillet over medium-high until butter has melted and mixture is sizzling. Add onion; cook, stirring often, until onion begins to brown, about 3 minutes. Add garlic; cook, stirring constantly, 30 seconds. Stir in corn, salt, and pepper; cook, stirring occasionally, until corn is tender, about 4 minutes. If desired, sprinkle with chives just before serving.
