Corn or maize (Zea mays subsp. mays), is a large grain plant that divided in six main types: flint corn, dent corn, popcorn, pod corn, sweet corn and flour corn. Already about 10,000 years ago, corn was domesticated by the indigenous communities in Mexico and it still plays a main role in the preparation of Mexican food dishes.
The leafy stalk of the corn plant produces separate pollen and ovuliferous inflorescences, also specified as ears, which are fruit, producing kernels. These kernels are often incorrectly referred to as seeds. Corn kernels often serve as starch in cooking practices.
Nowadays, corn is extensively cultivated all over the world. When it comes to numbers and volumes; there is more maize produced every year (in terms of weight) than of any other grain.
