Little known in Europe until the 12th century, the first eggplants that English-speaking people came into contact with bore egg-shaped fruits, probably white ones, hence the vegetable's name. In various parts of Europe, eating eggplant was suspected of causing madness, not to mention leprosy, cancer and bad breath, which prompted its use as a decorative plant. But by the 18th century it was established as a food in Italy and France (where it is known as aubergine). Eggplants are available all year, with their peak growing season extending from July to October. Florida provides the bulk of the domestic harvest; New Jersey is a major supplier during the summer months; California and Mexico are relied on to supplement the winter's supply. Freshness is important, so don't store them for very long.
