Is advent calendar chcoloate special?
Unless your advent calender is from the same company, and is the same kind (milk, semisweet, dark, etc) as your “bog standard chocolate bar”, it’s probably got different ingredients or different proportions of the same ingredients. Different candy makers use different kinds of cocoa beans, different flavorings, different proportions of chocolate to sweetener, etc. (That’s why Nestle chocolate tastes different than Hershey’s chocolate, which tastes different than Droste, which tastes different than Ghiradelli, etc, etc.) It’s also possible that the advent calendar chocolate is fresher than your “bog standard” chocolate.
I think it’s that advent calendars use really crap chocolate and that the taste is different and just appeals to some people. I can appreciate the difference in taste while knowing that it will never replace Green & Black’s cherry in my heart of hearts. Also I think the advent calendar chocolate evokes nostalgia for the taste from childhood, just as getting the calendar itself does. This may have positive impacts on the taster’s perception.
Best thing I can come up with is to buy your own non-disposable advent calendar and then fill it with Lindt.
