Karjalanpiirakka, also known as Karelian pasty, is a traditional Finnish pastry originating from the region of Karelia. It features a thin rye crust filled with rice porridge, mashed potatoes, or carrot filling. The pastry is often baked until golden brown and has a slightly crispy texture. Typically served warm, karjalanpiirakka is commonly enjoyed with a spread of butter or a mixture of butter and egg, known as munavoi. This dish is popular in Finland and has cultural significance, often served during celebrations and gatherings, reflecting the culinary heritage of the Karelian region.
