Maize, also known as corn, is a cereal crop that originated in South America, but is now grown around the world. Different varieties of maize yield cornmeal (the main ingredient of polenta), cornflour, sweetcorn and popcorn.
You’re most likely to see fresh maize for sale in the form of ears, or ‘corn on the cobs’. These are in season from August to October. Look for very fresh examples with green rather than brown husks, plump, tightly packed kernels and ears that feel heavy for their size. Canned sweetcorn is also available.
Sweetcorn is best eaten as fresh as possible, before its sugars are converted to starch. Corn on the cobs can be kept in the fridge for up to four days, or blanched and frozen.
