Nutritious and filling, the kalakukko is a typical food of Finnish culinary tradition and is MAINLY a mess of pork meat and fish. Besides being a delicious dish characterized by a certain shelf life, the origins kalakukko is curious: the idea of the dish, in fact, born in the villages of Eastern Finland and was adopted by the workers of the fields and woods as a full meal, comfortable to take with you, to be consumed at the workplace located away from home. The practicality of kalakukko is due to the shape, in particular to the crust that acts as a sort of pan which contains the meal inside. Finnish feeding, therefore, the preparation and consumption of kalakukko bring into play important anthropological and cultural values, and a trace of this traditional use, is still preserved today, in many people's preference for its use as a lunch box . From an economic point of view and food, in addition, the importance of the kalakukko resides in the fact that, historically, it allowed to take advantage of small fish, spiny, otherwise hardly accessible from the culinary point of view. A long slow cooking of the filling, (whose ingredients can clearly find variants), which occurs at relatively low temperatures, can soften the bones to the point of them dissolve in your mouth.
