Chocolate chips are about as “native’ a United States food item one can get that are not readily available or used in much of the rest of the world.
Back in the 70′s I was an exchange student to the Australian Outback–near Walgett, NSW. When I wanted to make something typically American for my host family I thought of chocolate chip cookies. They had never heard of such an item. My mother sent some, a big undertaking, and expensive, in those days.
To the best of my recollection, I saw none for sale and ate no foods in Panama, Mexico or Bolivia in the 70′s, 80′s or 90′s containing chocolate chips.
There were lots of chocolate bars in Mongolia, but no chips.
Ditto in Israel.
Back in the 90′s my friend Soon, from Korea, wanted to make Rice Crispy bars. To her _they_ were the quintessential American food.
The daughter of one of my friends from China plays the Guzheng. I finally saw a photo of one yesterday and listened to a musician performing on one here today.
The Guzheng similar to a harp. And a piano.
