Kalduny or kolduny (, , , , used in plural only) are stuffed dumplings made of unleavened dough in Belarusian, Lithuanian, and Polish cuisines, akin to the Russian pelmeni and the Ukrainian vareniki. In Slavic languages the word means “magicians” or “sorcerers”, but it is unclear how the word became associated with the dish. The origin of kalduny is uncertain: they may have originated with equal likelihood in the West (Germany or Czech lands) or in the East (brought by the Tatar-Mongols across Siberia and the Urals).
