Many people like to peel the husks and remove the silks when buying corn, but this is not actually the best practice. It's best to buy corn with its husks on.
This is because the outer husk helps protect the corn's moisture, keeping it fresh and flavorful. When cooking corn, it's best to remove the outermost thick layer of husk but leave the two innermost thin layers, and also clean the silks. This helps to preserve a unique corn aroma and makes it easier to cook. Generally, corn only needs to be boiled for about 8 minutes. Once cooked, it's best to remove it immediately and drain the excess water; otherwise, the flavor will not be as rich. It's worth noting that the broth cooked with the corn husks and silks is called "Dragon's Beard Soup" and is suitable for people with diabetes and high blood pressure.
