For starters, this was my take on the traditional Polish dumpling. So don't expect a very traditional recipe, at least for the sauce, (I think). For those of you who aren't familiar with this dish, let me elucidate. Pierogi are dumplings that are first boiled, then either baked or fried in butter and onions. They can be filled with a variety of fillings, ranging from mashed potato to meat to a dessert version with fruit inside. This recipe is for potato pierogi, but you can accommodate the filling to whatever you like. In addition, in this recipe I don't bake or fry the pierogi, instead I smother it in a creamy cheesy white sauce. It's up to you to make the sauce or not, nevertheless, I hope you will enjoy this recipe.
