A pierogie is a Polish dumpling. It is typically made of dough and a filling. The dough is usually made of flour, water, salt, and egg, and is made into small circlets and filled with things like potato and onion or cheese, cream cheese, fruits, etc. The dough is then folded in half and the edges are crimped, so the pierogie is in the shape of a half moon. The pierogie are then boiled in salted water until they float. They may also be pan fried with butter. * Contributed by: Zwolak, 2008
