Vatrushka (
Russian: ватрушка) is an
Eastern European pastry (
pirog) formed as a ring of dough with traditional white cheese
Tvorog in the middle, sometimes with the addition of
raisins or bits of fruit.[1] The most common size is about 5–10 cm (2–4 in) in diameter, but larger versions also exist. Vatrushkas are typically baked using a sweet
yeast bread dough. Savoury varieties are made using unsweetened dough, with onion added to the filling.[2][3][4]
The etymology of the word is uncertain. A widespread hypothesis derives the name from the word vatra meaning "fire" in some Slavic languages (Ukrainian for example). According to another version, the word is borrowed from the Romanian language, in which "vatra" meant "a kind of cake, cooked in the fire".[5] Alternative hypotheses trace it back either to the verb teret (тереть, "to rub" or "to grate") or to the term
tvorog (творог).[6][7][8]
