The best chocolate ever?

I don't know if this is (was) the best chocolate in the world, but for sure is the best chocolate I've ever tried...
Pierre Marcolini is a well known Belgian chocolatier and this carré was a present from a dear friend that went to Bruxelles and thought of me... I normally prefer dark chocolate, but I have to say that this incrusté of milk chocolate with pecan nuts and subtle perfumes of caramel was just astonishing!!! So wonderful that all I can show you is the beautiful box but not the chocolate, as it disappeared very quickly...
