Polish pierogi – stuffed dumplings are probably most well know Polish food specialty outside of Poland or maybe second best known after Polish kielbasa – sausage.
Polish pierogi have three most popular stuffing types- cottage cheese with potatoes (called Russian pierogi), ground meat and sauerkraut (fermented cabbage) with mushrooms. Still, you can find in Poland small specialized restaurants called “pierogarnia” which sell nothing else than pierogi and they come in tens of different flavors. During the summer, it is popular to eat pierogi stuffed with fruit like strawberries.
Pierogi can be served direct from boiling water and topped with melted butter with sauteed onions, or can be browned in a skillet after boiling and then served.

i too make up my own stuffings, just so mine can be a little different from the standard types you can buy at the supermarket. But they are all delicious 🙂
