Tesco have this new Bluberry dark chocolate hitting the shelves within the next two weeks, seems like just you thing! I tried it a while ago and it was surprisingly unique and very addictive.
Slightly off topic, has anyone gone a long period of time without chocolate and come back to it finding its far more bitter than you remember?
Have a friend who use to eat a ton of chocolate, but after giving it up for lent, he came back to the stuff and was near disgusted at how bitter it is. Now how cant eat chocolate but oddly has a craving for the taste of chocolate he 'remembers'.
