Many people like to peel off the husks and remove the silk when buying corn, but this is not the best practice. It's better to buy corn with the husks on. This is because the outer husk helps protect the corn's moisture from evaporating, thus preserving its texture. When cooking corn, it's best to remove the outermost thick husk, leaving the two inner thin layers, and wash the silk. This helps to retain a unique corn aroma and makes it easier to cook. Generally, corn takes about 8 minutes to cook.
Once the corn is cooked, it's best to remove it immediately and let it drain, otherwise its flavor will not be as rich. It's worth noting that the broth cooked with the corn husks and silk is called "Dragon's Beard Soup" and is suitable for people with diabetes or hypertension.
