Salzburg is truly a beautiful city with a lot to see and experience. I think especially the Fortress Hohensalzburg is a great place to visit.
Regarding Mozart Balls I find it quite interesting that there are many different manufacturers with different recipes. So there are quite a few different versions of them.
Have you also been to Salzburg? I also really liked Fortress Hohensalzburg :)
Yes, it was like 15 years ago, though. I'm pretty sure I visited the Mozart house as well, but the main thing I remember about the trip is the fortress.
That's great :)
