Juicy fresh corn on the cob gets an extra boost of sweetness when it's cooked in slightly sweetened water. You can use as much or as little sugar as you like. Try it several ways to figure out what level of sweetness you like best. Brown sugar will add a hint of molasses flavor to corn, while granulated sugar gives a pure, sweet taste. When done, sprinkle liberally with salt and butter for the perfect salty sweet side dish.
