Depends on the variety of corn. If it is sweet corn, boiling water for 10 to 15 minutes will cook it. If it is glutinous corn, old corn, sticky corn or black corn, etc., it needs to be boiled for 15-20 minutes. The best way to cook corn is to put the corn into the pot when the water is cold, so that the cooked corn is heated evenly, soft and sweet, and can lock the nutrients of the corn to a greater extent.
