There are tons of recipes for fruit pierogi if you google em, they usually include the recipe for the pasta as well. They’re little dumplings, basically ravioli. My fiance is polish and I make them for him on occasion with twarog and blueberries, (a simple milk cheese that’s really easy to make -you can skip the cheese and serve them with cream which is great too) boil them, then fry them in butter and sprinkle them with powdered sugar.
