How many minutes does it take for corn to cook

Corn is usually cooked for 15-20 minutes to fully ripen, and the specific time depends on factors such as corn variety, maturity, heat intensity, whether it has skin, and cutting method.

Sweet corn or glutinous corn with skin can be boiled over medium heat for about 15 minutes after water boils. At this time, the corn kernels are full and retain juicy water. If the corn is older or larger in size, it can be extended to 20 minutes to ensure that the center is fully ripe. Cooking with a pressure cooker can be shortened to 8-10 minutes, and steam can quickly penetrate corn cobs. Frozen corn can be boiled directly without thawing, and the cooking time needs to be increased by 3-5 minutes. Segmented corn ripens faster than whole corn, taking about 10-12 minutes.

It is recommended to keep 2-3 layers of outer skin and corn whiskers when cooking corn, which can lock in sweetness and nutrients. Water should completely submerge the corn, and a small amount of salt or sugar can be added to enhance its flavor. Using chopsticks to easily penetrate corn kernels indicates maturity, while excessive cooking can lead to the loss of vitamin B family. Special varieties such as purple corn have high anthocyanin content, and it is normal for the water to change color during cooking. It is recommended to cook colored corn separately to avoid color mixing. After cooking fresh corn, it should be immediately removed and drained to avoid nutrient loss caused by prolonged soaking. When refrigerated cooked corn is reheated, steaming it can better maintain its taste than boiling it in water. It is recommended to consume with milk or beans to increase protein absorption rate. For those with weak gastrointestinal function, the cooking time can be appropriately extended to 25 minutes to make starch easier to digest. It is advisable to control the consumption of 1-2 pieces of corn per time, and diabetes patients should choose low sugar corn varieties.
