Modern flavor technology permits recreating almost any flavor. So a novelty company might have the idea of selling regional flavors in candy to tourists, like baked-bean flavor in Boston or sourdough flavor in San Francisco. Only the company that had the idea happened to be in Japan, which has strong traditions of regional specialties like stuffed squid in Hokodate and a kind of noodle soup in Hokkaido. Thanks to the internet, I was able to try some of these out. The flavors are genuinely interesting, and offer great potential for Trick or Treat.
