To start, you'll need a few basic supplies: an ear of corn (obviously!), a microwave-safe dish, and a damp paper towel. Don't worry, I'll explain why the paper towel is crucial in a sec. Now, I know what you're thinking: "Why not just nuke the corn straight on the plate?" Well, my friend, that's a recipe for disaster - or at least a messy, unevenly cooked ear of corn.
The key to reheating corn on the cob in the microwave is to create a little steaming action. That's where the damp paper towel comes in - it helps to lock in moisture and heat, giving you a tender, juicy ear of corn. Simply wrap the corn in the paper towel, making sure to cover it completely, and place it in the microwave-safe dish.
