Pierogi are synonymous with Polish cuisine. They are hugely popular in Canada where they are a ubiquitous pub meal. Pierogi almost certainly trace their roots back to Bona Sforza and her bevy of Italian cooks. While they owe a lot to ravioli in their construction, the fillings are uniquely Polish. Following are three of the most popular fillings and the ones that we serve at Borsch. Make the filling and let it cool before rolling the dough out. You can make both the dough and filling ahead of time. Alternatively, pierogi freeze very well, just make sure you separate them with layers of baking paper or freezer paper, or they’ll stick.
The dough we use at Borsch is made like hot water dough, scalding milk is added which cooks the flour as it is mixed, resulting in a silky, pliable dough. The dough will keep, tightly wrapped in the refrigerator, for about 1 week. The dough is the same one we use for uszka, the soup dumplings that go in Polish borsch. The major difference is an extra fold.
