loopyloo and J52, with you all the way- well I would, wouldn't I ;)
Our favourite at the mo is Lindt 70% with a pinch of salt (in the chocolate, with don't sprinkle salt on it, lol, it is amazing and 2 squares are sufficient, suck slowly, every evening).
I'm afraid that the original Cadbury's milk chocolate didn't contain much chocolate in the first place- even less under Kraft's- and what little left replaced by USA Hershey's- yuk- it's all palm oil and no cocoa butter- and practically no chocolate either.
But a Cadbury's cream egg? Sorry, but no never, even in the days when I had a sweet tooth, it was absolutely and totally sickly inedible- sorry.
There is a huge shortage of chocolate beans, for environmental, weather/hurricanes and now Ebola- and the price is going through the roof- hence the changes happening in the cheaper ranges. Criollo chocolate beans from South America are the very best for luxury chocolate.
