Sweetcorn
Maize husks
Corn spears, baby corn or candle corn

Sweet corn also called sweetcorn, sugar corn, or simply corn, is a variety of maize with a high sugar content. Sweet corn is the result of a naturally occurring recessive mutation in the genes which control conversion of sugar to starch inside the endosperm of the corn kernel. Unlike field corn varieties, which are harvested when the kernels are dry and fully mature, sweet corn is picked when immature and eaten as a vegetable, rather than a grain. Since the process of maturation involves converting sugar into starch, sweet corn stores poorly and must be eaten, canned, or frozen before the kernels become tough and starchy. Sweetcorn kernels are one of the traditional ingredients of succotash.

Baby corn spears

Baby corn, candle corn or baby corn spears are a cereal grain taken from corn (maize) harvested early while the ears are very small and immature. It typically is eaten whole cob included—in contrast to mature corn, whose cob is considered too tough for human consumption. Baby corn is eaten both raw and cooked. Baby corn is most common in Asian cuisine. In Thai cookbooks, it is referred to as candle corn.

Corn husks

Corn husks refer to the leafy outer covering of an ear of maize (corn) as it grows on the plant. Literally, a husk or hull includes the protective outer covering of a seed, fruit or vegetable. The husks can be used as a wrap to cook foods such as tamales.
