Fresh corn should be sweet, crisp, and juicy. It is best eaten as fresh as possible, as it starts to lose its sugar content immediately after harvesting. The most common way to prepare fresh corn on the cob is to boil it, but roasting is also an excellent way to prepare it. To roast corn in the husk, first pull back the husks so that you can remove the silk, then replace the husks and tie them with kitchen string. Soak the corn in cold water for five minutes. Place corn on the grill and cook, turning occasionally.
