Pierogi (also perogi, perogy, pirohi, piroghi, pirogi, pirogen, pierogy, pirohy, pyrohy), from the Proto-Slavic "pir" (festivity), is the name most commonly used in English speaking areas to refer to a variety of Slavic semicircular (or, in some cuisines, square) boiled dumplings of unleavened dough stuffed with varying ingredients. In English, the word pierogi and its variants are pronounced with a stress on the letter "o".

They taste good with sour cream, chives, and bacon bits.
