Corn refers to the seeds, or kernels, of a plant grown in many varieties. The most commonly available is sweet corn, which is yellow or white. It is sold fresh by the ear in summertime or as canned or frozen kernels or frozen ears. When purchasing fresh corn, look for plump ears with undamaged kernels that fill the ear. For best flavor, enjoy fresh corn as soon as possible after purchase; store unhusked and in a plastic bag in the refrigerator. Use within 1 or 2 days.
To shuck corn and remove the kernels:
Strip off the outer green husks and inner fine silky threads. To remove the kernels, hold the ear by the pointed end and, with a sturdy knife, cut downward, turning the ear with each cut.
