This is a Ferrero Tronky:
And according to the guy's
blog, this is what they're like:
The bar itself is a large puffed wafer that breaks easily. This bar definitely wasn't made to take a beating. The wafer doesn't really have a taste but can be compared to chewing on a piece of thick newspaper. The inside is a hazelnut goo... Nutella!
I don't know about you, but they sound rather yummy, apart from the thick newspaper bit! You can't get them at CyberCandy yet, either.
