this is hopefully a simple question. I have had several friends from Eastern Europe, and they often visited with a bottle of a family-style distilled beverage. It is made with pretty much whatever fruits are available (I've had plum, prune, cherry, etc). The closest I can come with the pronunciation is "trweeka," but that is from memory so I could be slightly off. It would be found in the Ukraine, Czech Republic, Bulgaria, Moldova, Poland... those types of places. I am hoping someone may be familiar and know the proper name in Cyrillic and transliterated to English? I'd like to learn more about it.
I think you mean Tuica. This is a Romanian liquor, made from fruits. It is quite similar to Palinka, a Hungarian liquor with a protected name.
In the Czech Republic (and other countries around us) we have a drink made from fruits called "slivovice"
If you mean 'distilled', then in Poland it would be "bimber". But there's also a beverage made by mixing a strong alcohol (spirit) with various fruits (or coffee ;) ) and leaving it for half a year or longer. This is called "nalewka"
