To begin the process of making corn on the cob don't buy corn in the grocery store. Look for a farm stand, a neighbor or a local farmers market. The best corn is the corn that has not traveled at all and is still in its husks. A local farmer once told me that as soon as you shuck your corn it starts to age. So the best thing for corn is to wait till the very last minute before it goes in the pot to shuck your corn.
The way we cook corn is a tad different than others ... or at least it seemed
You see after the corn had been shucked it goes in a large stock pot of water, just high enough to cover the corn. Then add 2-3 tablespoons of butter and about a 1/2 cup of milk to the water. put on high and allow to boil for about 10 minutes. Good fresh corn will tell you when it is finished but smelling so wonderful you want to eat it right away.
The nice thing about making corn on the cob the way we make it is you really do not have to add butter or anything else, since it was all in the water the corn was boiled in.
Try this one day ... this may be the way you too may make corn from now on.
