This is traditional Finnish dish, and ‘Karjalanpiirakka literaly means ‘Karelian pasty’. Skin is made from rye flour, and its most popular filling is cooked rice. It is often topped with mashed hard boiled egg with butter, called Munavoi.
Kvass is a local carbonated drink made with rye malt. It is similar to the Kvass elsewhere in/around the Soviet Union areas. The Kvass in the present day tends to be produced with artificial sugar and flavor. Now I show a picture of Kvass with a flavor of wildberry.
