Corn is so much a part of American culture that its origin is recorded in histories and religious books of Native Americans dating back to the 8th century. By the 16th century, Indians were successfully cultivating many varieties of corn (maize) from Canada to Chile. Europeans first discovered corn in 1492 when Columbus saw vast acres of it in Cuba. And even though the Pilgrims learned to cultivate it in the 1600s, it wasn't until this century that sweet corn became popular. Clearly, this is one vegetable we'll never lose a taste for serving.
