Very interesting. And even The Netherlands is featured! Take a look at Ray's List of Weird and Disgusting Foods » "I have a theory that many (all?) cultures invent a food that is weird or disgusting to non-initiates as a sort of a "marker." The kids start out hating it, but at some point they cross over and perpetuate it (perpetrate it) on the next generation. Then they nudge each other when foreigners gasp."
