Nothing at all, from the cheaper end of the scale Cadbury's is fine, I like just plain dairy milks best out of their lot. I don't like caramel in chocolate, though fruit and nut is good.
The biscuit and raisin Yorkies are my favourite bar at the minute, mainly 'cos the work vending machine is holding a stock of them and you can get a twofer.
But I really like the dark rich stuff at the moment.
Ant - I was having a talk with my boss the other day and he said that he's partial to a double decker, but only when they're fresh and the mallow layer's soft. I don't think I've had one where it's been anything other than chewy and ended in a sticky mess. How would you even be able to tell if it's a fresh bar?!
I get mine from the work charity tuck shop, so could be a few weeks old.
The building is warm so it was nicely soft but not too sticky. I have had many a double decker in the past where the normally soft layer is hard and brittle.
Double Deckers are good. Fruit and Nut Cadbury's is pretty awesome. Mmm. I don't like Cadbury's Caramel chocolates, preter Galaxy for Caramel, and any other Galaxy choccies.
