Believed to have been first cultivated in Mexico, sweetcorn, Zea mays, was introduced into Europe in the 16th century and soon became a staple crop. Its deliciously sweet cobs can be barbecued to eat hole or boiled with the kernals separated to add to dishes. There are many sweetcorn varieties, ripening early, mid-season or late, and are therefore suited to different parts of the UK.
