Polish dumplings called pierogi.

I have made traditional Polish dumplings called pierogi. Dumplings are very popular in Poland, using an ancient recipe. It is said that they came to my country from China, where dumplings are prepared with cabbage, called jiaozi. In Poland, dumplings are an everyday food prepared for the day's main meal.  For special events such as on Christmas Eve, we make them with sour cabbage and wild mushrooms. Modern Polish cuisine they are made with different fillings, some very oriental and exotic.
