Leave the husks intact. Simply trim any excess silk that might be sticking out from the top, and remove any damaged outer leaves.
Lightly rinse the corn under cool water, allowing the husks to absorb some moisture. This creates steam inside the husk during cooking.
Place the damp ears of corn directly on the microwave turntable, or on a microwave-safe plate with 1/4 cup of water for extra moisture. Arrange in a spoke pattern if microwaving multiple ears.
Microwave on high power for 3-5 minutes for 1-2 ears. For each additional ear, add approximately 2 minutes to the cooking time.
Allow the corn to rest for 2 minutes before handling—the ears will be extremely hot and continue cooking slightly during this time.
Using oven mitts or a kitchen towel, grip the corn at the stem end and shake while pulling downward. The corn should slide out easily, leaving most of the silk behind with the husk.
Serve with butter or your favorite toppings and enjoy immediately.
