Corn is one of the most versatile and diverse crops in the world, with a wide range of varieties and uses. While fresh, sweet corn is a seasonal treat, there are many more types of corn that serve unique purposes, from popping and grinding to decorative uses. Let’s take a closer look at the different types of corn and what they’re best suited for.
Sweet Corn: A Fresh Delight
Sweet corn is one of the most popular varieties, prized for its tender, juicy kernels. Unlike regular field corn, which is left to mature and dry, sweet corn is harvested when the kernels are still immature, making it a vegetable rather than a grain. Sweet corn varieties are typically bred for their higher sugar content, making them a perfect choice for those who crave a sweeter flavor.
To determine if sweet corn is ready for harvest, peel back a small section of the husk and press a fingernail into a kernel. If a milky liquid oozes out, the corn is ripe for picking. Enjoy it fresh, or freeze it off the cob before it turns starchy for later use.
Popcorn: Fun and Ancient Tradition
Popcorn is a unique type of corn, known for its ability to “pop” when heated. Popcorn kernels contain a higher moisture content than other varieties. When heated, the moisture inside turns to steam, building up pressure until the kernel explodes, expanding up to 50 times its original size.
Popcorn has been enjoyed for thousands of years, with evidence of its use in ancient Mexico dating back at least 5,000 years. Today, it remains a favorite snack, often enjoyed at the movies, but it can also be popped on the cob in the microwave for a fun, nostalgic treat. If you’re growing your own popcorn, consider varieties like Glass Gem corn, known for its colorful kernels, which are perfect for popping.
Corn for Grinding: Creating Cornmeal and More
Certain types of corn are grown specifically for grinding into flour or meal. These are typically dried varieties and are essential for making cornmeal, the base ingredient for dishes like cornbread, tortillas, and cornbread. In the U.S., cornmeal is used to make grits, a Southern classic, often made from hominy (a type of processed corn).
Dent corn is the most common type used for cornmeal. It’s named for the small “dent” at the top of each kernel. Flint corn, which is harder and often more colorful, can also be used for both grinding and decoration. Flour corn, grown in drier regions, is used to create corn flour, which has a fine texture and can be substituted for wheat flour in gluten-free baking.
Drying Corn: Preserving Your Harvest
If you’re growing corn for drying, it’s important to ensure the cobs are fully dry before storage. Hang the cobs in a warm, dry, well-ventilated area, out of direct sunlight, to finish drying. Once dry, you can remove the kernels by rubbing two cobs together, then store them in an airtight container.
Dried corn is ideal for grinding into meal or flour, or for popping. Proper storage ensures that your corn will stay fresh and usable for months to come.
Conclusion
Corn is much more than just a staple food—it’s a crop with rich diversity and many uses. From sweet corn to popcorn, cornmeal, and decorative varieties, there’s a type of corn for every need. Whether you’re harvesting it fresh, popping it, or grinding it into flour, corn offers endless possibilities for delicious meals and fun activities.
