“
The time the first Europeans arrived in the New World, farmers there were harvesting more than a hundred kinds of edible plants–potatoes, tomatoes, sunflowers, marrows, aubergines, avocados, a whole slew of beans and squashes, sweet potatoes, peanuts, cashews, pineapples, papaya, guava, yams, manioc (or cassava), pumpkins, vanilla, four types of chilli pepper and chocolate, among rather a lot else–not a bad haul. It has been estimated that 60 per cent of all the crops grown in the world today originated in the Americas. These foods weren’t just incorporated into foreign cuisines. They effectively became the foreign cuisines. Imagine Italian food without tomatoes, Greek food without aubergines, Thai and Indonesian foods without peanut sauce, curries without chillies, hamburgers without French fries or ketchup, African food without cassava. There was scarcely a dinner table in the world in any land to east or west that wasn’t drastically improved by the foods of the Americas.
