Buttery, sweet and juicy, corn on the cob is a star of summer cookouts and picnics. National Corn on the Cob Day, on June 11, celebrates this simple pleasure, best eaten fresh with butter, salt and maybe a sprinkle of spices. Whether grilled, boiled or roasted, corn on the cob is a delicious reminder of the bounty of summer.
History of National Corn on the Cob Day
Corn, also called maize, was domesticated in southern Mexico about 9,000 years ago from a wild grass called teosinte. Teosinte had tiny cobs with only a few hard kernels. Over thousands of years, Indigenous farmers selected plants with larger cobs and softer kernels, creating corn.
Corn spread throughout the Americas and became a staple crop for many Native American peoples, often grown with beans and squash in a system known as the 'Three Sisters'. European colonists learned how to grow corn from Native Americans.
Sweet corn, the type usually eaten on the cob, has more sugar than field corn, which is used for animal feed, ethanol and processed foods. The United States is the world's largest corn producer. Who created National Corn on the Cob Day is not documented.
