This stunning salmon braid pie wraps succulent fresh salmon in a buttery, flaky yeast‑free dough enriched with cottage cheese. The filling—a savory duet of earthy mushrooms and vibrant spinach—rests on a cushion of breadcrumbs, while the pastry is folded into a beautiful plait that impresses at any festive table. Because the dough contains no eggs or yeast, it needs a lengthy chill; plan ahead to let the gluten relax and the flavours meld. The result is a tender, golden crust that shatters at the touch, revealing a perfectly cooked centre.
About This Recipe
In Russian home kitchens, kosa (braid) pies are cherished for their elegant presentation and forgiving dough. This version skips eggs and yeast entirely, relying on cold butter and cottage cheese to create a laminated texture reminiscent of puff pastry. The filling draws from classic flavour pairings: rich salmon, umami mushrooms, and bright spinach. Whether served as a showstopping main course or a hearty brunch centrepiece, this pie proves that simplicity and sophistication can coexist.
Ingredients
- 500 g salmon, trout, or sea trout fillet (skin off, in one piece)
- 300 g medium button mushrooms
- 150 g fresh or frozen spinach
- Salt and freshly ground black pepper, to taste
- 300 g all‑purpose flour
- 200 g cold unsalted butter
- 300 g cottage cheese (5% or 9% fat)
- 2–3 tbsp sour cream (if needed)
- ½ tsp salt
- Milk, for brushing
- Breadcrumbs, for sprinkling
Step‑by‑Step Instructions
Step 1: Make the dough
Cut cold butter into 1 cm cubes. In a bowl, whisk flour with salt. Add butter and rub it into the flour with your fingertips until the mixture resembles coarse breadcrumbs. Stir in cottage cheese with a fork.
Step 2: Chill the dough
Once the dough clumps together, transfer it to a plastic bag, press into a flat rectangle, and refrigerate for 2–3 hours.
Step 3: Cook the mushrooms
Clean and slice mushrooms thinly. Place in a saucepan over low heat, cover, and steam for 20 minutes, shaking occasionally. Remove lid, raise heat, and cook until all liquid evaporates, about 5 minutes.
Step 4: Add spinach
Cut spinach into 1 cm ribbons, add to mushrooms, and cook 7–10 minutes until wilted. Season with salt and pepper, then cool.
Step 5: Prepare the salmon
Trim the fillet into a neat rectangle. If it’s wide, cut lengthwise. Remove any pin bones.
Step 6: First lamination fold
On a floured surface, roll chilled dough into a 20×40 cm rectangle. Fold the top third down, then the bottom third up (like a letter).
Step 7: Second roll and fold
Turn the dough so the seam is on the left (like a book). Roll again into the same rectangle, then fold into thirds once more.
Step 8: Final chill
Wrap the dough in plastic and refrigerate for 40 minutes.
Step 9: Roll and trim
Preheat oven to 200°C. Roll dough on parchment into a rectangle about 8–10 cm longer and three times wider than the salmon fillet. Trim edges with a sharp vertical cut to expose layers.
Step 10: Assemble the filling
Mentally divide the dough widthwise into thirds. Sprinkle breadcrumbs over the middle third, top with mushroom mixture, then salmon fillet. Season generously. Cover with spinach.
Step 11: Braid the pie
Cut 1–1.5 cm wide strips at a 45° angle on both sides of the filling. Alternately fold strips from left and right over the filling to form a braid.
Step 12: Brush and transfer
Brush the braid with milk. Slide the parchment onto a baking sheet.
Step 13: Bake and rest
Bake for 35–40 minutes until deep golden. Rest on a rack under a cloth for 10–15 minutes, then transfer to a platter. Serve hot or warm.
Pro Tips for Perfect Results
If using frozen spinach, thaw it in the refrigerator, then squeeze dry before adding to the mushrooms. This prevents a soggy filling. For extra flaky layers, chill the dough thoroughly between folds—a planetary mixer can speed up the initial mixing, but hand‑rubbing works beautifully. Use a sharp knife to cut clean strips for the braid. A convection oven ensures even browning; if yours runs hot, start checking at 30 minutes.
Variations and Substitutions
Replace salmon with trout or even a firm white fish like cod. Swap spinach for chard or kale. For a vegetarian version, omit the fish and double the mushrooms—use porcini for deeper flavour. The dough also works beautifully for sweet fillings; try apples and cinnamon with a light dusting of sugar. If you’re short on time, use store‑bought puff pastry, but the homemade cottage cheese crust is worth the effort.
Frequently Asked Questions
Can I make the dough a day ahead?
Absolutely. Prepare the dough up to 24 hours in advance and keep it wrapped in the refrigerator. Let it sit at room temperature for 10 minutes before rolling.
How do I prevent the salmon from drying out?
Baking the pie just until the salmon is opaque—about 35–40 minutes—keeps it moist. A digital thermometer inserted into the centre should read 50–55°C for perfectly cooked fish.
Can I freeze the assembled pie?
Yes. Freeze the unbaked braid on a baking sheet, then wrap tightly. Bake from frozen, adding 10–15 minutes to the baking time. Brush with milk before baking.
What if my dough is too sticky?
Add 2–3 tablespoons of sour cream while mixing to adjust the moisture. If it’s dry, a splash of milk works. For sticky dough, chill longer before rolling.
Is this recipe gluten‑free adaptable?
Not directly, but you can experiment with a 1:1 gluten‑free flour blend. The dough will be more fragile, so handle gently and chill well. Use almond flour for a nutty twist, but note the texture will differ.
Can I use other mushrooms?
Certainly. Cremini, shiitake, or a mix of wild mushrooms add wonderful complexity. Just adjust cooking time for moisture content.
What’s the best way to reheat leftovers?
Warm slices in a 180°C oven for 8–10 minutes to revive the crisp crust. Avoid the microwave, which softens the pastry.
