Kalakukko

Kalakukko is a Finnish loaf in which small fish and pork are sealed inside a rye-flour crust and baked for a long time. It is a traditional dish of Savo, a region of eastern Finland, where the bread shell works like a cooking vessel. As the loaf bakes, the fish and pork release fat and juices into the filling, which keeps the meat soft and moist.

What it really is

A dough of rye flour, water and salt is shaped around a filling of small fish and pork, then sealed and baked, traditionally in a slow oven for several hours. The crust turns dark and firm, while the filling becomes tender and rich. The rye shell is part of the dish, not a lid: it holds in the juices and gives the loaf its dense, earthy flavour. Kalakukko is a bread-based meal, and the rye dough is its defining feature.

How it's served

• Cut into thick slices and served warm or at room temperature.
• Eaten as a hearty main course or a substantial snack, often with butter spread on the bread.
• Set on a board or plate with the dark crust still on.

How to write it on the menu

• Name the fish and the pork, for example "small fish and pork baked in rye", and name the fish species if you know it.
• Flag fish and rye on the allergen list. Rye is a cereal that contains gluten, so guests with coeliac disease need to be told.
• State whether the loaf is served warm or at room temperature, and whether butter comes with it.
• Give the portion as a slice or a weight, so guests know how much they are ordering.
