@nprofile1q... I suppose it's a standard artificial sweet flavour that was used in a country (Aus/NZ, probably) where fairy floss is the default name? Different companies running the distribution, different flavours might have become standard?
But I can't find any sources in the slop of web content that describe what flavour "fairy floss" is supposed to be. The default "cotton candy" flavouring that became dominant in North America is allegedly blue raspberry.
