To boil corn on the cob, the typical cooking time ranges between 3 to 10 minutes depending on the method and preference for tenderness:

• A common approach is to add the corn to boiling water and cook uncovered for about 3 to 5 minutes until the kernels are tender and golden. This usually takes about the time for the water to return to a boil after adding the corn

• Another method is to bring water to a boil, add the corn, cover the pot, and then turn off the heat. Let the corn sit in the hot water for about 10 minutes. This method keeps the corn tender and allows it to stay hot for up to 30 minutes without overcooking

• Some people prefer boiling for around 8 minutes or until the kitchen smells like corn, which is also a good indicator of doneness

• For very tender corn, boiling up to 10 minutes is suggested, but boiling longer than that (up to 30 minutes) is generally unnecessary and may affect texture

In summary, boiling corn on the cob for 3-5 minutes is sufficient for crisp- tender kernels, while 8-10 minutes or using the "turn off heat and let sit covered" method yields softer, fully cooked corn. The corn is done when kernels turn bright yellow and plump
