Pierogi (/pɪˈroʊɡi/ pih-ROH-ghee)[a], also known as varenyky, are filled dumplings of Central and Eastern European cuisines, made by wrapping unleavened dough around a savory or sweet filling and cooking in boiling water, or pan-frying. Pierogi which consist of noodle dough and have to be cooked in boiling water are associated with the Central and Eastern European kitchens where they are considered national dishes. Pierogi-like dumplings are popular in most Central and Eastern European countries as well as in Ashkenazi Jewish and modern-day American cuisines, where they are known under their local names.
Typical fillings include potato, sauerkraut, ground meat, cheese and fruits. The dumplings may be served with a topping, such as melted butter, sour cream or fried onion, or a combination of those ingredients.
