When you add milk to the liquid in which you cook corn on the cob, it keeps the kernels from becoming bitter.
- Place the water, milk, butter, sugar, salt, and red pepper flakes in a large, heavy pot and bring to a rolling boil over high heat.
- Add the corn, reduce the heat to a simmer, cover, and cook until tender, about 5 to 8 minutes.
- Remove the pot from the heat and let stand until needed.
- Drain and serve hot, either plain or with the condiments of your choosing, such as oil, butter or maple syrup.
