I remember when on a visit to India, it suddenly occured to me how much of the Indian diet depended on vegetables originally from the Americas, tomatoes, potatoes, bringles (aubergine) and chilli peppers all were imported after the discovery of the Americas by the Europeans. "What did Indians eat before that time" I asked my indian friends, but no one could come up with the answer at the time, although I'm sure there are scholarly studies of the history of indian food.
But it's interesting to imagine what we would be eating if these American veg didn't cross the Atlantic, there would be no fish and chips, no pasta sauce, no aloo gobi, no ketchup !
Newly developed blue tomatoes.
