As a Slovene, I have traveled to most Balkan countries. I noticed two things that seem specific to Slovenia, at least from my experience.

First is pizza burek. It is filled with cheese, ham and tomato sauce. In Slovenia it is very common, just like meat or cheese burek. We also have spinach and potato burek, but those exist everywhere in the Balkans. Pizza burek is the one I have not really seen outside Slovenia. Does pizza burek exist in your countries?

Second is how we order ice cream. A lot of people order half-half, meaning half of one flavor and half of another flavor in one scoop. Sometimes half-half is more expensive than just one flavor. Scoops in Slovenia are quite large, so you often get what feels like two scoops in one portion. I have not seen half-half ice cream to be common elsewhere. In Croatia, if you order half-half, you will still get it, but people might look at you a bit strange. Many Slovenes will first ask: “Može pola-pola?” (“Can I get half-half?”)

Are these things really specific to Slovenia, or do you have them in your countries too and I just haven't noticed?
