Karelian pasties, Karelian pies or Karelian pirogs are traditional pasties or pirogs from the region of Karelia. Today they are eaten throughout Finland as well as in adjacent areas such as Estonia and northern Russia. Today, the most familiar and common version has a thin rye crust with a filling of rice. Mashed potato and rice-and-carrot fillings are also commonly available. Butter, often mixed with chopped-up boiled egg (egg butter or munavoi), is spread over the hot pasties before eating.
