I present the only candy I know with a name both German and Spanish: the Kinder Bueno.
Let me start by pointing out that I love chocolate mixed with hazelnuts. I keep a jar of Nutella at work and at home, and I indulge now and again with some Italian Baci candies. However, the treat I found in Italy when I was there were these chocolate bars, and I immediately felt them call to me.
Now, the first thing to remember is that this bar is actually made by Ferrero, maker of those little golden wrapped hazelnut chocolate balls that are only advertised as belonging to the swankiest parties. Odds are they know their hazelnut.
What makes this treat different from every other hazelnut treat I've had is that this isn't just hazelnut blended into chocolate or sprinkled throughout. Instead, this is a hazelnut cream-filled wafer with a chocolate coating. Doesn't that sound luxurious?
The bar is also segmented, and when you break off a piece, hazelnut cream doesn't leak out everywhere, but when you bite into it, your tongue will get a tasty coating of flavor. It has a nice crunch to it with the wafer, and the chocolate is consistently creamy.
This is one of my favorite candy bars on the market, and I need to find a local Walgreens to see if they carry it nationally, or if that one shop was just special. Otherwise, looks like I might have to hit up Amazon.
