Under normal circumstances, ordinary sweet corn and fresh corn can be cooked in 10 to 15 minutes after boiling. If it is waxy corn or old corn, sticky corn, black corn, etc., then you need to add another 5 to 10 minutes. If cooking corn in a pressure cooker, cook for 3-5 minutes after the pressure cooker safety valve is bubbling.

Corn is generally boiled in a pot under cold water, which is slowly heated with cold water so that the corn can be cooked from the outside to the inside.

In addition, do not cook the corn for a long time after it is ripe, because if the corn is too long, the taste of the corn will be a little weaker and the taste will become poorer. Add a small amount of salt, which can enhance the taste and exude the fragrance, and soak before cooking to reduce the time it takes to cook corn.

Types of corn.

1. Sweet corn.

Sweet corn is one of the most popular corn varieties, also known as vegetable corn, is a crop of the genus Poaceae corn, its morphological characteristics are the same as ordinary corn, but the seeds of sweet corn are thin, and the plants are divided into three types: ordinary, strengthened and super sweet.

2. Waxy corn.

Waxy corn, also known as sticky corn and waxy corn, is named after the coarse waxy endosperm in the kernels, which is native to China, and the growth of the plant is strong, the plant is compact, the leaf color is dark green, and it has extremely high disease resistance.

3. High-oil corn.

High-oil corn is a type of high value-added corn, which is characterized by high oil content of grains, and is a corn variety specially used for oil extraction, but the current yield of high-oil corn in China is small.

4. Burst corn.

Popping corn is a type of corn used to make corn flowers, native to the United States, and has fewer ears and seeds, the seeds have starch, the texture is harder, and the seeds are rich in color, with white, yellow, purple or orange markings.

5. Colored corn.

Colored corn is an annual erect herbaceous plant, is a hybrid variety of corn, its plant height is 100-150 cm, because of the variety of grain colors, has high ornamental value, so it is often collected after maturity and placed indoors for ornamentation.

Corn is generally cooked after boiling for about 15-20 minutes, which needs to be distinguished according to the type of corn and cooking equipment

1. Boil fresh corn and cook in a pot under cold water for 20 minutes. Because fresh corn itself has more moisture, it is relatively shorter to cook for a short time, in order to ensure that it is cooked thoroughly, it is recommended to cook in a pot under cold water for 20 minutes

2. Boil fruit corn and cook in a pot under cold water for 15 minutes to cook. Because fruit corn is usually smaller and has a higher sugar content, it is easier to cook, and it is generally enough to cook in a pot under cold water for 15 minutes;

3. Boil white waxy corn and cook in a pot under cold water for 25 minutes. Due to the high starch content of white waxy corn, it is relatively difficult to cook, so it is recommended to cook it for at least 25 minutes before eating;

4. Cook in a rice cooker, and reduce the above bases by about 5 minutes each. Due to the high pressure of the rice cooker itself, the cooking time can be appropriately shortened by 5 minutes;

5. Cook in a pressure cooker, the above base can be reduced by 10 minutes. Because the pressure cooker is very high, the heating is also fast and stable, and the corn can be cooked in 6 minutes after steaming.

The corn will be cooked after boiling for ten to twenty minutes. Fresh corn is very fresh and tender, the water content is very rich, so it is easier to cook after the pot, generally the tender corn can be cooked for about 10-15 minutes, but if it is waxy corn, black corn or older corn, the cooking time will be slightly longer, generally need to be boiled for about 5-10 minutes. If you don't know whether the corn is cooked or not, you can use chopsticks to press the corn kernels, and the cooked corn kernels will be more firm and elastic when pressed with chopsticks.

Selection of cornLook at the corn leaves, if the leaves are green, there are no yellow leaves and are relatively fresh, the corn is fresher, if the leaves are shriveled and dark yellow, it means that the corn is not fresh. Look at the cut where the corn is broken and if the cut is black. It means that the corn is not fresh.

If the cut is light in color, it means that the corn is fresh.

If the roots of corn are dry and waterless, it means that the corn is not fresh. If the corn roots are fresh and tender, the corn is fresher. Look at the softness and hardness of the corn, pinch the whole corn with your hands, if it is soft and there is juice oozing, it means that the corn is fresh.

Generally, corn can be cooked after boiling for about 15-20 minutes, but it needs to be distinguished according to the type of corn and cooking equipment

2.Boil the fruit corn and boil in cold water for 15 minutes. Lead deficiency is due to the fact that fruit corn is usually small, high in sugar, and easy to cook. Generally, 15 minutes of cold boiling is enough.

3.Cook the white waxy corn and cook it in cold water for 25 minutes. Due to its high starch content, white waxy corn is difficult to cook. It is recommended to cook for at least 25 minutes before eating.

4.Cook in a rice cooker, and subtract about 5 minutes from each of the above bases. Because the rice cooker itself is stressful, the cooking time can be shortened by 5 minutes.

5.Cook in a pressure cooker. The above base can be reduced by 10 minutes. Because the pressure cooker is very high, the heating is also fast and stable. Generally, corn can be cooked after boiling for 6 minutes.

Cooking tips for boiling corn:

1) Boiled corn should be eaten while it is hot, and if it is heated for the second time, the taste will be completely different and not delicious.

2) You can add some sugar to the water at the same time to boil the corn, so that the boiled corn is sweeter and softer.

3) When boiling corn, you can also add half a cup of milk to the rice cooker, so that the cooked corn tastes more fragrant.

Eight minutes after the water boils.

If it is sweet corn, it is enough to boil it for 10-15 minutes after boiling with water, boil it for about 10 minutes for the more tender ones, and cook it for a long time if it is a little older, generally not more than 20 minutes, otherwise the taste of the corn will decline, and it is enough to cook it for 5-8 minutes in the Gekai pressure cooker.

It is best to soak corn for 20-30 minutes before turning on high heat to cook. This can effectively retain the vitamins of the corn itself, and it tastes fragrant and chewy.

Nutritive value. The vitamin content in corn is very high, 5-10 times that of rice and wheat, and the nutritional value and health care of corn are the highest among all staple foods. The riboflavin and other high nutrients contained in corn are very beneficial to the human body.

It is worth noting that the nutritional value of special corn is higher than that of ordinary corn, and the moisture, active substances, vitamins and other nutrients of fresh corn are also much higher than that of old corn.

Corn silk contains crude fiber, crude protein, polysaccharides, and crude fat. The chemical composition of corn silk has changed greatly in different varieties and at different times. The contents of total phenols and total anthocyanins in corn silk reached the highest at the milky maturity stage, and the total flavonoids and antioxidant activity were the highest at the silking stage, but the contents of total phenols, total flavonoids and antioxidant activity in sweet corn and white corn were the highest at the silking stage.

When you are boiling corn, if you want to eat the tender corn, you can boil the corn for fifteen minutes after boiling, at this time the corn is ripe, and the sweet taste is strong, and the taste is better, but if the corn itself is relatively old, it should be appropriately extended for cooking time.

The longer the corn is cooked, the higher its unique anti-free radical activity will be, and the anti-aging effect will be obvious after people eat it, so for some middle-aged and elderly friends, it is best to cook corn for a period of time, scientists have proved that corn is boiled for more than 50 minutes, and the anti-free radical activity is the highest.

2. Choose non-glutinous coarsely ground corn ballast, and the time to cook porridge is shorter. Doing so is more conducive to blood sugar control.

3. The so-called corn silk is actually the pollen of corn, as a part of the reproductive organs of plants, corn silk does contain complex chemical components, such as flavonoids, amino acids, minerals and some amino acids. However, at present, it is difficult for these substances to act directly on the body's metabolic system.

1. In the case of fruit corn, it is usually enough to boil for 10 to 15 minutes after the water is boiling.

2. If it is white waxy corn, it is usually boiled for more than 20 minutes after boiling.

Fruit corn is usually smaller, has a higher sugar content and is easy to cook, and is usually cooked in a pot under cold water for 15 minutes. White waxy corn is high in starch, so it is more difficult to cook, and it is recommended to cook it for at least 25 minutes.

If it is an ordinary variety of fresh corn, it has more moisture, and the cooking time is shorter, and it is cooked in a pot under cold water for about 20 minutes. In addition, if we use a pressure cooker to cook corn, the time will be greatly shortened, because the pressure in the pressure cooker is very high, and the heating is also fast and stable, and the corn can be cooked in 6 minutes after steaming.

Cook corn to pay attention to the problem

1. With 2 layers of outer skin: If you want to cook corn to be more sweet and delicious, do not completely remove the outer skin and corn whiskers of boiled corn, you can only peel off the outer few layers of outer skin, leaving 2 layers of outer skin and all the corn whiskers inside to cook together, and the corn can retain the sweetness well.

2. Add a spoonful of salt to cultivate: When boiling corn, adding a spoonful of salt to the water can increase the electrolytes in the water, help the corn to be heated and stable, and the corn will be sweeter due to the salt eaten. Boiled corn can add sugar to the water, so that the corn is more sweet and soft.

When cooking corn, you can also add a small half cup of milk to the rice cooker, so that the cooked corn tastes more fragrant.
