I made these for dinner tonight, and while they were absolutely delicious, mine I'm sorry to say looked nothing like the ones in the picture. I think I need a better nonstick pan, the filling also oozed out quite a lot, I think I might try sealing them more like gyoza next time, and seeing how that works, they really are delicious tasting though, even if mine weren't pretty, very good with sour cream too. :)
Wow! These were fabulous. I didn't cut the wrappers into circles, but rather made the pierogies into flatter, larger triangles. All the more surface to get all crispy-licious frying in the butter! I think they would be even better with a few sauteed mushrooms and onions in the filling. I cooked 4 of them tonite and popped the other 8 into the freezer to enjoy later (lay them flat on a cookie sheet to freeze individually, then wrap, bag and store).
