This milk chocolate bar from the Spanish chocolatier Trapa, from what I've read, uses the same century old recipe that the Trapesian monks created in 1891 in Palencia, Spain. I have also seen the bittersweet chocolate version in the Supremo line, but there are ones with white chocolate, rice crispies and almonds. They also make several other lines of chocolate, with specialty ingredients, some with Swiss chocolate. The ingredients of this bar are definitely milk chocolate, with sugar, cocoa butter, cocoa mass, whole milk powder, hazelnuts (pieces), defatted cocoa powder, soy lecithin, flavours and salt (an unusual ingredient for chocolate bars). There is no indication of the cacao content or origin.
How does it taste? Fairly good, sweet, the bar smells of the hazelnuts as you open the package, and there are lots of hazelnut pieces within. I think I could buy this again.
