Works great if you are only cooking one or two ears of sweet corn at a time. Cooking time varies by microwave. My microwave takes about 3 1/3 to 4 minutes to cook an ear of sweet corn.Directions: Wet a paper towel, and wring out. Wrap the ear of corn in the moist towel, and place on a dinner plate. Cook in the microwave for 5 minutes. Carefully remove paper towel, and enjoy!
