I've only recently discovered pierogies, but of course I wanted to try making my own. I couldn't find a filling that was exactly what I wanted, so I adapted my own. I got the wrapper recipe from a fantastic cookbook called "A world of dumplings". They make a nice sturdy wrapper, I didn't have any problem with any of my piergoies splitting open when cooking them, and they have a consistancy I loved. I used low-fat sour cream and it worked great.
