Finland's most iconic pastry — oval rye crust shells filled with creamy rice porridge (or sometimes mashed potato), baked until the edges crisp and served warm with munavoi (a Finnish egg-butter spread). Originally from the Karelia region, Karelian pies are now eaten across Finland at every bakery, café, and home. The combination of the slightly sour rye pastry with the rich, buttery egg topping is deeply satisfying and uniquely Finnish.
