I'm a bit confused. Does this apply to absolutely all truffle oil? For years I have bought one particular type, which has the following list of ingredients: Extra virgin olive oil, 1% truffle juice from white truffle (Tuber Magnatum pico), 1% natural aroma, 1% truffle aroma. So it's supposed to contain both the real thing and truffle aroma. It costs like €11 for a 55 ml bottle. Is much of the flavour the taste of the real truffle it contains, or the truffle aroma that it also contains?
