After the cooked corn is cold, it can be heated by microwave oven, which can quickly turn the cold corn into hot corn. It is recommended to put it in a basin, otherwise it will be very dry if it is hot. Glass basin and high-temperature plastic basin should be used for water basin. Metal will reflect microwaves and easily catch fire. After the corn is heated in the microwave oven, it may shrink and lose water, and the taste inside and outside will be different.
