First of all, to prepare the corn on the cob with butter, wash the cobs and check that they have no imperfections, even under the leaves but without detaching them.
Take a saucepan and bring the water to a boil, salt it, add the corn on the cob and cover them completely with the milk. Let them boil for about 20 minutes.
Drain them, then, and lay some pieces of butter on top that will melt very quickly, giving the cobs an intense flavor. Let’s salt and pepper them. The corn on the cob with butter are now ready to be served.
