My co-worker Amor S. brought me some chocolate truffles that she got on a recent trip to Austria.
The round one on the left was dark chocolate filled with pistachio paste, somewhat like marzipan but not very sweet. I liked it, and the chocolate seemed very high quality. It had a rich deep chocolate taste, and it melted readily in my mouth.
The one on the right was similar, being dark chocolate with hazelnut paste. It was somewhat fruity tasting but I am not sure there was any fruit. Anyway, it was really good too.
Amor said this brand seemed popular in Austria and Germany with both locals and tourists, and I agree it was very good. Now I want to visit Vienna!
