Pierogi

Pierogi are traditional Polish dumplings filled with various ingredients and served with sour cream or melted butter.

Ingredients - Serves 6

In a large bowl, combine the flour, water, egg, and salt. Mix until a dough forms.
Knead the dough on a floured surface until smooth and elastic, about 5 minutes.
Cover the dough with a damp cloth and let it rest for 30 minutes.
In a skillet, melt the butter over medium heat. Add the chopped onion and cook until golden brown.
In a separate bowl, mix the mashed potatoes with the sautéed onions, sour cream, salt, and pepper.
Roll out the dough on a floured surface until it is about 1/8 inch thick.
Using a round cookie cutter or a glass, cut out circles from the dough.
Place a spoonful of the potato filling in the center of each dough circle.
Fold the dough over the filling to form a half-moon shape. Press the edges together to seal.
Bring a large pot of salted water to a boil. Cook the pierogi in batches for about 5 minutes, or until they float to the surface.
Remove the cooked pierogi from the water using a slotted spoon and transfer them to a plate.
Serve the pierogi hot with sour cream or melted butter.
