Horseradish
In Central and Eastern Europe horseradish is called khreyn (in various spellings like kren) in many Slavic languages, in Austria, in parts of Germany (where the other German name Meerrettich is not used), in North-East Italy, and in Yiddish (כריין translitered as khreyn).

In Ashkenazi European Jewish cooking beet horseradish is commonly served with gefilte fish. Red beet with horseradish is also used as a salad served with lamb dishes at Easter called sfecla cu hrean in Transylvania and other Romanian regions.
