Ingredients

• 600 g, plus extra for dusting rye flour
• 100 g all-purpose wheat flour
• 450 ml warm water
• 2 tsp salt, for the dough
• 2 tbsp butter, softened, for the dough
• 700 g fresh vendace (muikku), cleaned, heads removed
• 300 g pork belly, sliced thin
• 2 tsp salt, for the filling
• 3 tbsp butter, melted, for brushing

Instructions

1. Step 1: Combine the rye flour, wheat flour and 2 tsp salt. Add the warm water and softened butter and knead into a firm, smooth dough. Let it rest for 15 minutes.
2. Step 2: On a rye-floured surface, roll the dough into an oval about 2 cm thick, leaving the center a little thicker than the edges.
3. Step 3: Lay half the pork belly slices in the middle of the dough. Layer the vendace on top, salting each layer, then cover with the rest of the pork.
4. Step 4: Fold the dough up over the filling and pinch the seams tightly closed, wetting them with water so they seal. Patch any cracks with leftover dough.
5. Step 5: Bake on a parchment-lined tray at 250°C (480°F) for 30 minutes to set the crust.
6. Step 6: Brush the crust with melted butter, wrap the loaf in foil and then parchment, and lower the oven to 125°C (255°F). Bake for another 5–6 hours.
7. Step 7: Unwrap and brush with butter again. Wrap in a clean towel and rest for 1 hour.
8. Step 8: To serve, cut a lid off the top crust and spoon out the filling with pieces of crust. Serve with cold buttermilk and butter.
