Ethnic foods always morphs into a different version of the original. When I worked in Japan with a native Korean (great guy, ex Korean Marine, Vietnamese war veteran, excellent welder). We talked about the foods available in the Korean neighborhood in Yokohama, he said that they had great tasting food, but to him it tasted more like Japanese food. He didn’t like some of the kimchi you could buy in the grocery stores in Japan, he said it didn’t taste right. The dominant cultures flavors will always seep into the newly introduced cuisine.
There is a curry that is served all over Japan, that descends from a dish that was once served on British warships. So it’s an Indian dish that was anglicized, then it had Japanese flavors added to it. Now, the most common way this curry is served is on a plate with rice and a hamburger patty, the post WWII American influence on the dish.
I wasn’t impressed with the pizza I ate in Italy. But the Calzones were absolutely wonderful. The gelato, fruit cakes (I don’t remember the Italian word for these), cured meats, and cheeses were all very good!
That trip to Italy was 27 years ago, and we only visited northern towns (my girlfriend at the time was attending classes at the University in Bologna). The south is really where pizza is a significant food.
