The specific cooking time depends on what corn it is. If it is tender corn, it usually takes 8 to 10 minutes after the water is boiled, and it takes 15-20 minutes for older corn, but it should not exceed 20 minutes. If you use a pressure cooker, it only takes about 6 minutes to cook. If it is white waxy corn, it usually takes more than 20 minutes after the water is boiled. If you use a pressure cooker, it will take more than 20 minutes.

However, waxy corn, old corn, sticky corn, black corn, purple corn and so on. After boiling, add 5- 10 minutes. When cooking corn, you can add a little salt if you want to be sweet, and a little baking soda if you want to keep the beneficial ingredients from losing. In addition, it is best to save the last two skins for cooking before cooking corn.

Matters needing attention in cooking corn

1, it is best to cook corn in cold water. The purpose of boiling corn in cold water is to let the heat slowly run into the corn, so that the cooked corn is more waxy and the nutrients in the corn can be preserved to a greater extent.

2. If the corn is boiled in boiling water, it will suddenly be heated and the corn skin will become thicker, so that the cooked corn will be crisp and the taste will not be so good.

If you make soup with corn, you'd better cook it with cold water, so that corn can be used to refresh yourself and the soup is delicious.

4. If the corn kernels are hard and there is no hollow phenomenon, it means that such corn is ripe. If we peel corn kernels and they spill juice, it means that the corn is not ripe and needs to be cooked for a while.
