The Swiss chocolatier Maestrani makes a number of different chocolate bars, this one features two things I like, dark chocolate (60% cacao content) and whole hazelnuts (20%). The ingredient listing is just okay, cocoa mass, sugar, hazelnuts, cocoa powder, cocoa butter, butterfat (milk), soya lecithin and vanillin.
How does it taste? I'm always pleased when I find a bar combining hazelnuts and dark chocolate, most of the ones made are with milk chocolate. The chocolate is quite tasty, though the hazelnuts don't taste fantastic, and I quibble about the distribution of the whole hazelnuts - some pieces have none or one, some 3 hazelnuts - better care would make this a more enjoyable bar. I would buy this bar again.
