"Curry and rice" is one blend of different food cultures.
Here are some others.
Spaghetti comes from Italy, but a Japanese chef created " spaghetti Napolitan" in Japan.
He made it with a special tomato sauce and named the dish "Napolitan" after Naples in Italy.
California rolls come from the U.S.
For many years, sushi wasn't popular in the U.S. because people there didn't usually eat raw fish.
So some Japanese chefs used avocado.
Also, they wrapped the rice on the outside because many people didn't like seaweed.
Food travels around the world, and changes in each place.
It's very interesting.
