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

• Boil fresh corn in a large pot of boiling water for about 3 to 5 minutes. This timing starts once the corn is added and the water returns to a boil. At around 3 to 4 minutes, the corn is tender and sweet, though signs of kernel shriveling may appear if boiled longer

• Some prefer to boil for about 8 to 10 minutes, especially for full ears, or until the kitchen smells like corn and the kernels turn a golden yellow. This longer time can produce softer corn but risks overcooking

• An alternative method is to boil the corn briefly, then turn off the heat and let the corn sit covered in the hot water for 10 to 30 minutes. This allows the corn to cook gently and stay warm without overcooking

In summary, for tender, flavorful corn, boiling for 3 to 5 minutes is typical, with the option to use residual heat for longer gentle cooking. Boiling beyond 5 minutes can lead to overcooked, less sweet corn
