How long does it take for corn to ripen after the water boils

After the water boils, corn usually needs to be cooked for 10 to 15 minutes, and the specific time depends on factors such as corn variety, maturity, and firepower.

Fresh sweet corn kernels are full of water and should be boiled over medium heat for about 10 minutes before consumption. This type of corn has a low starch content and a tender texture, and can achieve the best taste after a short period of heating. During the cooking process, a strong aroma of corn can be smelled wafting out, and lightly poking with chopsticks can feel the particles soften before turning off the heat. If you prefer a softer and more glutinous taste, you can extend it for 2 to 3 minutes, but excessive cooking can lead to the loss of water-soluble vitamins.

The old corn or waxy corn needs to be cooked for a longer time. Usually, after the water is boiled, it is adjusted to a medium low heat to continue to cook for more than 15 minutes. This type of corn has a high starch content and a tight texture, requiring sufficient time for heat to penetrate into the core. When checking the ripeness, you can observe whether the corn kernels are swollen or cracked. If a toothpick can easily penetrate the corn cob, it indicates that the corn kernels are ripe. If cooking with a pressure cooker, turn off the heat after 6 to 8 minutes and let the excess heat simmer until the pressure is naturally relieved.

When cooking corn, it is recommended to keep 2 to 3 layers of bracts to lock in moisture and nutrients. Adding a small amount of salt or baking soda to water can help soften dietary fiber. After cooking, immediately remove and drain to avoid losing flavor due to prolonged soaking. Corn is rich in antioxidants such as lutein and zeaxanthin, and high-temperature and short-term cooking can maximize the preservation of nutritional value. For those with weak gastrointestinal function, the cooking time can be appropriately extended to facilitate digestion and absorption.
