To cook sweet corn on the cob by boiling, the typical recommended cooking time is about 5 to 7 minutes once the water is boiling and the corn is added. For best results:
- Peel the husks and remove the silks.
- Bring a pot of water to a boil.
- Add the corn to the boiling water, cover, and cook for 5 to 7 minutes.
- Remove the corn from the water and serve hot with butter and salt.
Some variations suggest cooking for about 3 to 5 minutes for tender kernels or up to 10 minutes if you turn off the heat after adding the corn and let it cook in the hot water. Overall, 5 to 7 minutes is a common guideline for tender and juicy sweet corn.
