This was served as part of the first course at the Ymir 2025 feast.
What, Where, When
- A conjectural 16th-century Rus pastry, combining two separately-attested fillings from the Domostroi — onion and poppyseed — into a single vatrushka form.
- The method is modern; the filling pairings and dough type are reasoned from period sources.
Discussion
A note on the name: “vatrushka” is an 18th-century Russian term for a broad family of filled pastries, not a 16th-century word. The underlying form — a small round of dough with a filled well — has many regional variants and predecessors. “Almost every province had its version. In Arkhangelsk they made shanezhki with fillings. In Kostroma they made kuleika, in Voronezh — mandryka. There were also little filled dough pies called kokorka, kokurka, kruzhalka and dozens of other variants. And there were shangi made with pot cheese and potatoes that were very similar to vatrushki.” I use the word vatrushka here for recognizability rather than period accuracy; the dish is a conjectural reconstruction of a form the Domostroi references generically as an “onion tart” or a “pie stuffed with poppy seeds.”
The Domostroi, a mid-16th century Russian household management text, mentions onion tarts and poppyseed-filled pies as distinct bakery items in several passages describing fast-day and feast-day spreads. On pages 195-196, in a listing of Lenten dishes, it describes “onion tarts, fritters, pies stuffed with poppy seeds, sweet jellies, and unleavened bread.” A nearly identical listing appears at page 200.
Most relevant to this dish, is a passage at page 203 describing weekend Lenten fare that includes “pancakes stuffed with poppy seed-flavored cottage cheese and served with butter.” The poppyseed-plus-cheese filling combination is therefore not itself conjectural — it is attested in the Domostroi, though in blintz form rather than tart form. What is conjectural here is the structure that takes an attested cheese-and-poppyseed filling and places it in the well of an enriched bun, and then uses the separately-attested “onion tart” as the logic for a caramelized-onion topping. The form combines two period filling traditions; the distribution between filling and topping is a modern choice driven by taste and by the affordances of the bun shape.
A savory vatrushka with a cheese filling and fried-onion topping is also a recognizable form in modern Russian baking, which at least suggests the pairing is not wholly without culinary-tradition precedent — though the strength of any line of descent from 16th-century practice to the modern version is difficult to establish and I am not claiming one.
The dough itself is a heavily-enriched yeasted dough with roughly 57% butter and 38% egg by flour weight — closer to a brioche than to a lean bread. The Domostroi does not specify dough formulas for its tarts and pies, but its general description of household provisioning (rye, wheat, oats, buckwheat, peas, and hemp, along with butter, eggs, and dairy) supports the plausibility of an enriched wheat dough for a festival or holiday baked good. A rich dough also made sense for a vatrushka specifically, where the bun is structural: it needs to hold a generous well of cheese filling without collapsing or going dry.

Poppyseed and Onion Vatrushka
A conjectural Rus pastry combining two Domostroi-attested fillings: a ricotta-and-poppyseed filling baked into the well of an enriched yeasted bun, topped after baking with slow-caramelized onions.
Ingredients
- Caramelized Onion Topping:
2 medium onions (about 1.5 lb / 700g), thinly sliced
2 tbsp butter (more as needed)
Salt, to taste
- Poppyseed and Ricotta Filling:
275g (about 10 oz) whole-milk ricotta, drained if very wet
1 tbsp poppyseeds
Salt, to taste
- Enriched Dough:
2 tbsp whole milk, warmed to lukewarm
7g (1 packet) instant yeast
430g all-purpose or bread flour
8g salt (about 1.5 tsp)
3 large eggs (about 165g liquid egg)
245g (about 17 tbsp) unsalted butter, softened but still cool, cut into tablespoon-sized pieces
Directions
- Make the onions (can be done a day ahead): melt the butter in a heavy pan over medium-low heat. Add the sliced onions and a pinch of salt. Cook slowly, stirring occasionally, for 45-60 minutes, until deeply golden and jam-like. Add additional small knobs of butter only if the onions are sticking or drying out — you do not want them greasy. Taste for salt. Cool and refrigerate until ready to use.
- Make the filling: stir the ricotta and poppyseeds together. Taste and add salt as needed. Refrigerate until ready to use.
- Bloom the yeast: warm the milk to lukewarm (around 100°F). Stir in the yeast and let sit for 5-10 minutes until foamy.
- In the bowl of a stand mixer fitted with the dough hook, combine the flour, salt, eggs, and yeast-milk mixture. Knead on medium-low speed until the dough comes together and begins to pull away from the sides of the bowl, about 5-7 minutes.
- With the mixer running, add the butter one piece at a time, waiting for each addition to be mostly incorporated before adding the next. This is the critical brioche-style step — take your time, and do not rush. Once all the butter is in, continue kneading until the dough is smooth, glossy, and elastic, about 5-8 more minutes. If the dough is very sticky, add a small amount of additional flour, but knead well first — the dough will tighten as it is worked.
- Transfer the dough to a greased bowl, cover, and let rise for about 1 hour, until puffy but not necessarily doubled — enriched doughs rise slowly.
- Divide the dough into 12 equal portions (about 70g each). Shape each into a smooth ball, flatten slightly, and press a shallow indentation into the center with your thumb or the bottom of a floured jar. Arrange on parchment-lined baking sheets with room to expand. Cover and proof for 30-45 minutes, until noticeably puffed.
- Preheat the oven to 350°F. Just before baking, press a deeper well into the center of each bun — go most of the way down without punching through — and spoon a generous tablespoon of the ricotta-poppyseed filling into each well.
- Bake for 20-25 minutes, until the dough is deeply golden brown and the cheese filling has just begun to take on color at the edges.
- While the vatrushki are still warm, top each with a small mound of the caramelized onions. Serve warm, or rewarm gently in a low oven before serving.
