Loading...A traditional Savonian specialty from eastern Finland, this hearty rye loaf encases chunks of freshwater fish and salt pork in a thick, slightly sweetened rye crust. After a long, slow bake, the dough becomes firm and the filling steams in its own juices, producing a portable, almost meal-in-one bread that was once carried by loggers into the forest. Serve in thick wedges with cold butter and a strong rye beer.

Ingredients
For the rye dough
- 3 cups dark rye flour
- 1 cup all-purpose flour
- 2 tsp active dry yeast
- 1 tsp salt
- 1 tbsp molasses or dark syrup
- 1 1/4 cups lukewarm water
- 2 tbsp melted butter or lard
For the fish filling
- 1 1/2 lb skinless freshwater fish fillets (perch, pike, trout, or whitefish), cut into 1-inch chunks
- 6 oz salt pork or pork belly, sliced thin
- 1 1/2 tsp fine sea salt
- 1/2 tsp freshly ground black pepper
- 1 tsp crushed juniper berries (optional)
- 2 tbsp chopped fresh dill
- 1 small yellow onion, finely diced
For the glaze
- 1 egg yolk
- 1 tbsp water
- 1 tsp coarse sea salt for sprinkling
Directions
- Sprinkle the yeast over the lukewarm water with a pinch of sugar; let stand 8 minutes until foamy. Stir in molasses, salt, melted butter, rye flour, and enough all-purpose flour to form a stiff, slightly tacky dough.
- Turn the dough onto a lightly floured surface and knead 8-10 minutes until smooth. Place in an oiled bowl, cover, and let rise in a warm spot for 1 hour, or until nearly doubled.
- While the dough rises, prepare the filling: toss the fish chunks with salt, pepper, juniper, dill, and onion. Layer half the pork slices on a plate and set the rest aside.
- Punch down the dough and divide into a two-thirds piece and a one-third piece. Roll the larger piece into a thick round about 12 inches across to form the base and walls; keep it on parchment.
- Mound the fish in the center of the dough round, leaving a 2-inch border. Layer the remaining pork slices over the top of the fish, letting some fat drape over the fish.
- Roll the smaller dough piece into a 10-inch round for the lid. Drape it over the fish mound and fold the bottom edges up over the top, pinching tightly to seal completely so no juices escape. Shape into an oval, foccaccia-style loaf.
- Transfer the loaf on its parchment to a baking sheet. Cover loosely and proof 30 minutes. Meanwhile, preheat the oven to 325°F (160°C).
- Whisk the egg yolk with water and brush generously over the entire loaf; sprinkle with coarse salt. Bake on the lower-middle rack for 1 1/2 hours.
- Increase the oven to 350°F (175°C) and bake another 1 1/2 to 2 hours, until the crust is deep mahogany and sounds hollow when tapped (internal temperature should reach 200°F).
- Wrap the hot loaf in a clean kitchen towel and let rest at least 30 minutes so the filling sets. Slice into thick wedges and serve with cold butter and tangy mustard.
Cook’s Notes
- Traditional kalakukko uses tiny whole vendace (muikku); you can substitute smelts or even sardines, heads removed, for an authentic touch.
- The long, low bake is essential: too hot and the crust cracks before the fish cooks; too short and the filling stays raw. Test by inserting a skewer through the thickest part – it should slide into fish easily.
- If the crust browns too quickly, tent loosely with foil after the first 2 hours to prevent burning while the interior finishes.
- Wrap leftovers in foil and reheat in a 300°F oven for 15-20 minutes; the rye crust softens then crisps again beautifully.
- Serve with a Finnish lager, cold buttermilk, or a small glass of aquavit to complement the rich, savory filling.
