I love white chocoloate, even though true chocoholics consider it to be blasphemy. Some of them go so far as to say it shouldn't even be called chocolate, just because it doesn't contain any chocolate. Can you imagine that?
How is it that you haven't had, like, Toberlone? Even us septics have that imported and commonly available.
Urban legend, though an understandable one. While Belgium did go this route, they got most of their cacao imported from Mesoamerica, where it originated.
Gonna need a source for that, because I'm pretty sure cocoa/cacao was grown a lot in the Belgian Congo as well (though, I should probably go find a source for that myself, it's been a good decade since I studied it and my memory could be faulty). Not disputing that cocoa/cacao came from Mesoamerica, but it certainly grows very well in parts of Africa and it would have been about four hundred years between the start of the Columbian Exchange and Leopold's Congo.
