Sweet Corn: Sweet corn is a specific variety of maize that is harvested at a relatively early stage while the kernels are still in the “milk stage.” At this point, the kernels are sweet and tender, and they contain higher sugar content compared to other maize varieties. It is consumed as a vegetable and is known for its sweet, mild flavour. Sweet corn is often eaten on the cob, but it can also be cut off and used in various dishes, such as salads, soups, and side dishes. It is the type of maize you find in grocery stores for fresh consumption.
Maize: Maize is a broader term that encompasses all types of corn, including sweet corn. Maize refers to the entire species of Zea mays, and it includes various types and varieties of corn, some of which are not sweet. Maize can be grown for various purposes, such as animal feed, industrial processing, and other culinary uses. While sweet corn is one of these varieties, there are also others like dent corn (used for animal feed and processed products), flint corn (often used decoratively), and flour corn (milled into cornmeal or flour).
