A traditional Karelian food item, now enjoyed all over Finland. The crust is typically 50% rye flour. To be considered a Karelian Pie, the filling must be of short-grain rice, potatoe, or barley. There are similar pastries with less rye flour in the crust, and some with a carrot filling. The traditional condiment for Karelian Pies is munavoi, a mixture of hard-boiled eggs and butter.
