The most commonly found varieties of sweet corn are yellow, white, and bicolor.
In Season: Corn is in season from May through September but peaks in late summer.
What to Look For: Look for ears that are fully encased in bright-green husks and topped with golden-brown tassels. Pull back just enough of the husks to make sure the kernels are in tight rows.
How to Store: Since corn begins to lose its natural sweetness as soon as it is picked, fresh corn is best eaten the day it is purchased; if not, you can refrigerate ears in their husks for up to two days.
