This Meatless Monday, we feature corn, with growing, storage and prep tips, as well as recipes for Corn and Bean Salsa and Roasted Corn on the Cob from Vermont Fresh: A Fruit and Vegetable Handbook.
Corn is one of North America’s oldest and most symbolic foods. Together with winter squash and beans, corn was one of the “three sister” foods that were staples of the Native American diet for centuries. Fossilized grains of corn date the crop to many thousands of years ago. Corn was one of the first crops to be cultivated and traded by Native Americans; there were widespread fields of it by the time European explorers appeared. Also called “maize,” corn was integral to the diet of early American colonists, who learned how to grow it from Native Americans. Corn, which is actually a grain, can be ground into flour like wheat, but some varieties are eaten in their immature state as “sweet corn,” which is commonly considered a vegetable. Second to rice, corn is the world’s most widespread crop, with the United States leading production. It is perhaps the world’s most heavily genetically modified crop. Today, corn is grown for livestock feed, corn-syrup production, ethanol fuel, and plain old eating (which is probably the most well known-type of corn).
Sweet corn is most often seeded directly into the garden once the soil has warmed and frost is no longer a threat, but it can also be transplanted to get a jump on the growing season and avoid kernel-eating pests (start seeds 4 weeks before setting outside). Corn is a warmth-loving vegetable that needs full sunlight. Seeds should be planted about 1 inch deep with about 6 inches between plants. Don’t forget to leave walking space between rows! Corn needs to be well fertilized with compost. Corn is ready to harvest when the ears are fat, have dried-down silk tassels, and their kernels squirt liquid when pierced. You can peel the husk back on an ear to check for readiness, but leave the remaining ears fully intact to avoid damage from pests. Corn is susceptible to attack from raccoons.
Corn is best eaten as soon as possible after it is picked. It can be refrigerated for a short period of time. Once an ear of corn is removed from the stalk, the kernels’ sugars begin turning to starch, making the corn mealy. If your corn cannot be consumed fresh, freeze loose kernels or on the cob after blanching.
Sweet corn has a high fiber, protein, and potassium content. Sweet corn is very easy for humans to digest. The fresher the corn, the less starch it will contain and the more vitamins and minerals.
When buying corn, choose full ears with bri
