Where did the apples in Japanese Curry come from?
Curry and apples were both introduced to Japan in the late 19th century. Curry did not receive widespread popularity until the beginning of the 20th century and apples were not introduced to the curry rue until the 1960s (When the sweeter honey and apple curries increased their popularity with children). In 1963 House Foods Corp introduced House Vermont Curry made with honey and apples.
