There is no clear regulation on how long the corn is cooked, because there are many kinds of corn, and the size, hardness and shape of different kinds of corn are different, so how long the corn is cooked depends on the specific situation.

But in general, it takes about 15-25 minutes after the corn is cooked, which can be seen by observing the color and hardness of the corn. If the color of the corn darkens and the press becomes soft and elastic, it means it is ripe.

If you still can't judge, you can taste directly. If it still smells of starch, it means it is not ripe yet. If it becomes sweet and delicious, it means it is ripe.

Will corn harden when cooked for a long time? It depends.

Corn will harden when cooked for a long time, which is caused by too much water loss. So in general, as long as there is enough water, even if the corn is cooked a little older, it will not harden.

However, if you don't pay attention to the amount of water during cooking, the amount of water for cooking corn is insufficient, and the corn may become hard after cooking for a long time. So when cooking corn, you must add enough water and pay attention to the cooking time.

Is the water boiled in corn drinkable? Yes

Corn is a nutritious food, which contains crude fiber, crude protein, polysaccharide, crude fat and various vitamins and minerals. According to Compendium of Materia Medica, corn is sweet and non-toxic, and has the effect of regulating stomach and appetizing. After boiling, the active ingredients will be dissolved in water, so drinking boiled water from corn is good for health.

4 Cook corn with cold water or hot water and cold water.

Because corn is directly cooked with hot water, the outer layer of corn will be directly heated and cooked, while the inner layer is in a relatively raw state, and the cooked corn is easy to harden and grow.

If you cook with cold water, the water temperature will rise slowly, and the corn will be heated more evenly, so the cooked corn has a uniform taste and taste, so it needs to be cooked with cold water.
