When I was a kid in the mid-1970s, we lived in Stuttgart, Germany for 3 years. There wasn’t a lot of American food available off base, and ethnic (non-European) food was similarly scarce. Eventually, we found a Chknese place near the square where they held the Christkindlmarkt every year. And they had somethkng on their menu I have never seen anywhere else: a giant spring roll.
I mean, comparable in size to a chimichanga, stuffed with sprouts, cabbage, pork, onions, etc., and fried. A complete dinner. I can only guess it was a specialty of that particular place, because no other Chinese person I’ve asked about it knew what the hell I was talking about. Who knows? Maybe it was something they came up with to satisfy the local Germans, kind of like how Chinese cuisine gets Americanized here.
