Corn will not grow old if there is enough water. However, cooked corn will harden after heating, mainly because the corn itself loses too much moisture during the secondary cooking process. The cooking time of corn is determined by the variety and utensil selection, and the taste of cooking different varieties is also different. If you use a rice cooker, it usually takes an hour to cook. If you use a gas cooker, it takes about 20 minutes. If you use a pressure cooker, it takes about 15 minutes.

Corn is divided into sweet corn and waxy corn. Sweet corn is suitable for cooking soup, while waxy corn is suitable for boiling and eating directly.

When boiling corn, it is best not to peel off all the outer layers. Leave two or three layers so that the corn will taste more authentic and more fragrant.

Be sure to put the pot under cold water, so that the cooked corn will not only be delicious, but the corn will not explode.

Don’t add too much water. If you add too much water, the sweetness will be cooked out. Adding a little salt will make the corn more fragrant and taste better after cooking. Don't cook it for too long. It depends on how much you cook. It usually takes about 15 minutes for it to be fully cooked.
