The ideal boiling time for corn on the cob varies depending on the method and personal preference, but generally falls within these guidelines:

• A common and effective method is to bring water to a boil, add the shucked corn, cover the pot, then turn off the heat and let the corn cook in the hot water for about 10 minutes. This method prevents overcooking and keeps the corn tender and sweet

• If you prefer to keep the heat on, boiling corn for about 3 to 5 minutes after the water returns to a boil is sufficient for tender kernels. Cooking longer than 5 minutes tends to overcook the corn, causing kernels to shrivel and lose sweetness

• Some cooks suggest boiling for 8 minutes or until the kitchen smells like corn as a sign that it’s done, with the kernels turning a bright golden yellow

In summary, for perfectly boiled corn on the cob:

• Boil water, add corn, then turn off heat and cover for about 10 minutes (gentler method).
• Or boil corn in boiling water for 3-5 minutes uncovered (quicker method).
• Avoid boiling longer than 5-8 minutes to prevent overcooking.

Both approaches yield tender, sweet corn, with the first method being more forgiving and the second faster
