I found this recipe on another website and thought it worked well. The dough turns out a bit sticky so you'll need plenty of flour on your rolling pin and surface. Makes (2) dozen large pierogi (5" dia. cutter).
I use a stand mixer with the flat beater to mix the ingredients. After about a minute, replace the flat beater with the spiral hook and knead the dough until it is firm and consistent. Rest the dough for 30 minutes with damp cloth over bowl.
To stuff pierogi:
* Before stuffing the pierogi, put a BIG pot of salted water on the stove to boil.
Roll out some dough on floured surface until about 1/16ï¿½ - 1/8" thick.
Cut out circles.
Put a heaping teaspoon of your filling into the middle of your dough circle.
Dip your finger into a cup of water and moisten half the edge of the circle. Then bring up lower half of circle to meet moistened half and seal together with your fingers. If you find your fingers sticking to the dough while doing this, dip them into a handy cup of flour.
Then pinch the edges together. Be very careful not to puncture the dough.
Lay the completed pierogi on a floured surface. Repeat process with all your dough circles.
Don't have the water boiling too vigorously while cooking the pierogi.
GENTLY slide the pierogi into the water. Boil until all of the pierogi rise to the top - about 7 minutes.
