Kalakukko

Ingredients

Dough

• 600 grye flour
• 200 gplain flour
• 450 mlwater
• 2 tspsalt
• 50 gbutter, melted

Filling

• 800 gsmall vendace or perch, gutted and left whole
• 400 gfatty pork belly, sliced
• 2 tspsalt
• 1 tspblack pepper

To finish

• butter, for sealing and rubbing

Directions

1. Make a stiff dough with the rye flour, plain flour, water, salt and melted butter, and knead it for 10 minutes.
2. Rye dough is heavy and does not become elastic like wheat. It should be firm and workable rather than springy.
3. Rest it 30 minutes under a cloth.
4. Roll it out into a thick oval, about 1.5 cm, leaving it thicker at the centre and thinner at the edges.
5. Keep it thick. This crust is a cooking vessel first and bread second, and a thin one splits and leaks fat into the oven.
6. Layer the whole small fish and the pork belly slices alternately down the middle of the oval, salting and peppering as you go.
7. The fish go in whole and ungutted of their bones. Five hours of sealed baking dissolves the small bones completely, which is the entire reason for the long cooking.
8. The pork fat is not optional. It bastes the fish from inside and keeps the whole thing from drying out.
9. Bring the long edges of the dough up over the filling and pinch them together firmly along the top.
10. Fold and pinch the ends closed, then smooth every seam with wet fingers.
11. Seal it completely. Any gap lets steam out and fat in, and the loaf dries into a brick.
12. Bake at 250°C (480°F) for 20 minutes to set the crust hard.
13. Take it out, rub the whole loaf with butter, wrap it tightly in foil or baking paper, and return it.
14. Drop the oven to 150°C (300°F) and bake for a further 4 to 5 hours.
15. Hot first to set the shell, then low and long to melt the bones. Skipping either stage gives you either a leaking loaf or a bony one.
16. Rub it with butter again on coming out and let it rest, still wrapped, for 30 minutes.
17. Cut the top off as a lid and spoon the filling out, eating the crust alongside.
18. It is a Savonia speciality, made to be carried by fishermen and field workers, and it keeps for days without refrigeration.

Technique

• Muikku, vendace, is the traditional fish and its small size is what makes the bone-melting work.
• It is sold at Kuopio market and has protected designation status in Finland.
• It travels and keeps extremely well, which is the whole reason it exists.

Substitutions

• Small perch, roach or whitebait in place of vendace.
• Streaky bacon in place of pork belly.

Variations

• Made with perch, as ahvenkukko.
• With a layer of barley groats under the fish.
• Smaller, as individual loaves.

History

A large baked pastry with a rye crust enclosing a filling of fish, most traditionally vendace or perch, layered with pork fat, most strongly associated with the Savonia region of eastern Finland, where it developed as a portable, long-keeping food well suited to fishermen, farmers and travelers needing a meal that could survive hours or even days without refrigeration. Its thick rye crust, baked for an extended period at low heat, both cooks the fish filling thoroughly and creates a dense, protective seal that helps preserve the contents for later eating, sometimes over the course of several days after baking. Kalakukko remains closely tied to Savonian regional identity specifically within Finland, and it has received European Union protected geographical status recognizing its specific Savonian origin.
