Field Corn and Sweet Corn: Why They Are Not the Same Thing

Field Corn and Sweet Corn: Why They Are Not the Same Thing

At first glance, it may seem that corn is just corn: yellow kernels, green leaves, an ear of corn — what could really be different? That is why the question in the image looks simple, but the answer may actually surprise many people.

Sweet corn is the tender corn we usually boil in summer, grill, or add to salads. It is harvested while still young, when the kernels are soft, juicy, and full of sugar. That is why it has such a pleasant sweet taste and is easy to chew. But this stage does not last long: after harvesting, the sugar in the kernels gradually turns into starch, so sweet corn tastes best when it is fresh.

Field corn, however, is a completely different story. It is usually not grown to be eaten straight from the cob. It matures for much longer, becoming harder, drier, and much starchier. This is the type of corn most often used as animal feed, or for making corn flour, grits, starch, syrups, oil, and even biofuel. If you try to boil a cob of field corn, it may look familiar, but the taste will not be the same: the kernels are tougher, less sweet, and not nearly as juicy.
