More on pierogies:
Cut the dough into square pieces. Put some potato mixture filling in the middle of the square. Fold up the dough in a triangle shape, pinching your edges securely to keep all the filling inside. This is important, the edges must be very secure.
Toss the triangular shaped pierogies into a pot of boiling water. Boil for about ten minutes. By the way, I have to ask, what do you think of my penguin tiles in my kitchen? I've always been very happy with them but recently one of my adult daughters commented that the penguins are kind of odd, meaning, by default, that I am kind of odd.
After they've boiled for ten minutes, put the pierogies in a frying pan and saute' them in butter and onions, tossing gently for maybe ten minutes - til tender and a little browned. (see photo at top)
Serve and enjoy.
