History

Corn or maize is native to America but is now grown throughout the world. The Māori were given maize by American sailors, which they grew and ate both fresh and fermented.  The fermented corn was known as kānga. Its strong smell didn't appeal to Pākehā who ate corn mainly as a grain. Eventually, a sweet form was developed, hence the name sweetcorn, it wasn't until the 1960s that sweetcorn became a popular fresh vegetable
