I found this, and a milk version, in a European delicatessen, I see from the box that it is made by Kraft Foods, at least their Poland facilities. I like how it contains whole hazelnuts (at 23% content, it is far less than the 34% in the Lindt Grand Hazelnut bars, but at ½ the price, it is worth it). It looks like this just makes the Dark category (46% cacao content), the ingredient listing lists sugar first, followed by cocoa mass, hazelnuts, vegetable oil, butterfat, soya lecithin as an emulsifier and vanillin.
How does it taste? Pretty good, not bad for a cheap chocolate bar, good whole hazelnuts. I think I might buy this bar again.
