Indeed that is what I thought after I posted my photo.. chocolate would have done it although on this bar milk isn't written it's dark.
I also thought that the photo chain is ook good way to learn to think out of the box if it comes to photography.

You have a good stock of chocolate? Lucky you, the only chocolate I see is Milka and it changed, it's as if it's as if it's rubber and it has a very strange structure which shows at high temperatures.

Now I go for a bite before the evening is over.
Thanks for replying.
