But in Civ-terms, it is precisely the foreign Ingredients that can be traded with Cultural Influence going with them, which is what makes the term 'cuisine' a bit of a misnomer technically, but still a reasonable over-arching term to cover what we are talking about: foreign influences in Food ranging from complete recipes to individual ingredients so different (like tomato or potato) that they change many 'native' dishes completely.
And, come to think of it, the potato is a good example: the thinly-sliced fried potato known variously as French-Fred Potato in the USA,
Pomme frits in Germany, 'chips' in England, was originally an experimental French concoction fed to, among others, the American minister to France, one T. Jefferson, who brought the recipe back to the USA, from where it went back to Europe and international standing. In this case, regardless of the actual origin, the dish is considered American largely because of its association with American fast-food franchises in the 20th century, which ties the whole concept back with the Corporations, if we so desire and as
@BuchiTaton suggested.
