Rasstegai are small, open-faced pies that are a cherished part of Russian culinary tradition. Typically served alongside clear broths or soups, these delicate pastries feature a tender yeast dough and a savory fish filling. The name comes from the Russian word "rasstegat’," meaning "to unbutton," referring to the characteristic opening left in the center. This recipe, adapted from Gastronom magazine, combines two types of fish: cooked pike or catfish and raw salmon, for a textural contrast that elevates the humble pie to an elegant starter.
About Rasstegai
Originating in medieval Russia, rasstegai were traditionally served in taverns as a quick, satisfying bite alongside a bowl of hot soup. The open top allows diners to pour broth directly into the pie, moistening the filling as they eat. Today, they remain a beloved classic, often featured at festive tables or as a refined appetizer. The use of sparkling mineral water in the dough gives it an airy lightness, while the dual-fish filling offers a sophisticated depth of flavor. For best results, use a reliable planetary mixer to knead the dough to a smooth, elastic consistency.
Ingredients
For the dough: 500 g all-purpose flour, 10 g active dry yeast, 1 tablespoon sugar, 1 teaspoon salt, 250 ml sparkling mineral water (slightly warmed), 60 ml vegetable oil.
For the filling: 300 g pike fillet (or catfish), 200 g salmon fillet (or other red fish), salt, freshly ground black pepper, vegetable oil for frying.
For assembly: 1 egg, beaten, for glazing.
Step-by-Step Instructions
Prepare the dough
In a large bowl, whisk together the flour, yeast, sugar, and salt. Gently warm the mineral water to about 35°C, then stir in the vegetable oil. Pour the liquid into the dry ingredients and mix until a shaggy dough forms. Turn it out onto a lightly floured surface and knead for 8–10 minutes until smooth and supple. Alternatively, you can use a food processor to combine the ingredients quickly. Place the dough in an oiled bowl, cover with plastic wrap, and let rise in a warm place for 1 hour, until doubled in size.
Prepare the fish filling
While the dough rises, cut the pike fillet into 1.5 cm cubes. Season generously with salt and pepper. Heat a splash of vegetable oil in a skillet over medium-high heat and sear the pike cubes until golden and just cooked through, about 3–4 minutes. Set aside to cool. Slice the salmon fillet into thin, bite-sized pieces. Season with salt and pepper but leave it raw – it will cook perfectly inside the oven.
Shape the rasstegai
Punch down the risen dough and roll it out on a floured surface to a 1 cm thickness. Using a round cutter or a glass with a diameter of 8–10 cm, cut out circles. On each circle, place a spoonful of the cooked pike, then top with a piece of raw salmon. Pinch the edges of the dough together to form a triangle, leaving the center open so the filling is visible. Repeat with remaining dough and filling.
Second proof and baking
Line two baking trays with parchment paper and arrange the pies, spaced apart. Cover loosely with a clean kitchen towel and let rise for 20 minutes. Brush the dough (avoid the filling) with beaten egg. Bake in the center of a preheated oven at 200°C for 10–12 minutes, until golden brown and puffed. The salmon should be just cooked through and very tender. Serve immediately, ideally with a side of hot fish broth or Ukrainian borscht – pour the broth into the opening just before eating.
Tips for Perfect Rasstegai
- Use sparkling mineral water for a lighter, airier dough; still water will work but yields a denser texture.
- Do not overwork the dough after the first rise – handle it gently to maintain the air bubbles.
- For an even more luxurious filling, add a spoonful of crème fraîche or a pinch of dill to the pike cubes before assembling.
- A non-toxic air fryer can also be used: bake at 180°C for 8–10 minutes, checking often.
- If you don’t have pike, any firm white fish (cod, haddock) works excellently.
Variations
Rasstegai are endlessly adaptable. Replace the pike with minced pork or chicken for a non-fish version. For a vegetarian twist, use sautéed mushrooms and caramelized onions. The dough itself can be enriched by adding an egg or using milk instead of water – try an espresso machine for a quick morning brew alongside these pies? Not quite, but a steamy bowl of ukha (Russian fish soup) is the ideal companion. You can also experiment with different sealing shapes: instead of triangles, create a braided edge or a simple round opening.
FAQ
Why is the center left open?
The open top allows diners to pour hot broth directly into the pie, keeping the filling moist and adding an extra layer of flavor. It’s also a signature visual element.
Can I make the dough a day ahead?
Yes. After the first rise, punch it down, wrap tightly, and refrigerate overnight. Let it come to room temperature for 30 minutes before rolling out.
What type of fish is best for the raw topping?
Salmon is classic, but trout or Arctic char are excellent substitutes. Use the freshest sashimi-quality fish for food safety.
Can I freeze unbaked rasstegai?
Absolutely. Assemble them on a tray, freeze until solid, then transfer to a freezer bag. Bake from frozen, adding 3–5 minutes to the baking time.
What should I serve with rasstegai?
They are traditionally served with clear fish broth, ukha, or solyanka. A crisp green salad with a lemon vinaigrette also pairs beautifully. For a modern twist, try them with a dollop of sour cream and fresh dill.
How do I prevent the dough from becoming soggy?
The key is to not overfill and to ensure the cooked pike is well-drained. Also, avoid pouring broth into the pies until just before serving – keep it separate on the table.
