Karjalanpiirakka is a traditional pasty consisting of various fillings wrapped in a thin rye crust. It is traditionally formed into an oval shape, and the top is always left open to showcase the creamy filling that is nowadays mainly prepared with rice or barley porridge and mashed potatoes.

When baked, each piece is brushed with melted butter and usually enjoyed as a hearty breakfast or lunch. Traditionally, Karelian pasty is served topped with munavoi—a creamy butter and egg spread.
