When I was younger, my father's job had him travelling overseas every few years, and one of the best things about that was the souvenirs he brought back. When he went to Germany, he brought back an assortment of mini Ritter Sport squares. Of course, these can be purchased in the United States, but that was my first exposure to them.
Since then, all kinds of different flavors have popped up, and I still run across the odd (not necessarily new) flavor, just waiting to be tasted. At a local Fresh Market (think Whole Foods but smaller), Ritter Sport Marzipan was on sale, and I couldn't resist. It came highly recommended by both the checkout clerk and the customer ahead of me in line.
The dark chocolate bar was absolutely gorgeous with just the right amount of gloss. A quick break released the wonderful aroma of almonds and cocoa, and from the first taste, I was hooked. The marzipan had a wonderfully gritty texture that reminded me of cookie dough (since they can serve a similar purpose), and the taste reminded me of amaretto liqueur.
Although the smooth, mild dark chocolate would have been okay on its own, it was a wonderful match for the marzipan. It was difficult to put this bar down, and it is close in the running to my beloved Butter Biscuit for my favorite Ritter Sport squares. One small issue I had was that the marzipan was soft and moist for the most part, but there were some dry spots scattered throughout the bar.
