It happens to food too. The "traditional" foods are never from just one place and it's always evolving and somewhere along the way someone adds their local cultural twist to something from the outside and it's suddenly so much better.

I cooked a recipe recently that was based on a dish that was made for American GI's in Japan after WWII ended. Okinawan Taco Rice

Now that's the only way I want to eat taco meat ....
