For corn on the cob, roll the ear up in waxed paper and twist the ends. Microwave for 2 min. for each ear.
For whole kernel corn, put it in a glass Pyrex dish with a lid. Add about 2 Tbs. of water, for steam. With the lid on, microwave it for 4 minutes. Pour the liquid off, add butter and salt and microwave for another 1 minute. It tastes like fresh from the garden.
