This is a classic piroshki recipe. You make these turkey and cheese piroshki in three steps: make the dough, cook the filling, and then assemble the piroshki. It’s easiest to do with a dough press  but you can build it manually. If so, be sure to seal the edges well with the tines of a fork.
For the Piroshki Dough
- 3 1/2 cups flour
- 1 teaspoon baking powder
- 1 teaspoon salt
- 1 tablespoon granulated sugar
- 1/2 cup cold butter
- 2 large eggs
- 1 cup sour cream
- Sift the flour, baking powder, salt, and sugar into a bowl. Cut the butter into 1/2-inch cubes and add it to the flour. Cut the butter into the flour with a pastry knife until it is the consistency of oatmeal.
- In another bowl, whisk the eggs and sour cream together until it is smooth.
- Add the egg mixture to the flour mixture and stir into a mass. Remove the dough ball to a floured counter and knead for a few minutes to make a smooth dough. Cover the dough ball and chill it in the refrigerator for an hour.
For the Piroshki Filling
- 1 lb ground turkey
- 1/2 cup diced onion
- 2 tablespoon butter
- 3/4 cup water
- 1/2 teaspoon garlic powder
- 1/2 teaspoon salt
- 1/4 teaspoon pepper
- 2 tablespoons flour
- 3 tablespoons fresh parsley or 1 tablespoon dried
- 1 cup grated cheese
- Melt butter in skillet. Brown ground turkey in butter, then add diced onion and cook until onion is tender.
- Sprinkle on flour, garlic powder, salt and pepper.
- Stir in water and parsley, cook for a minute until thickened. Set aside.
To Assemble and Bake the Piroshki
Preheat the oven to 375 degrees.
- Divide the dough in half and return one half to the refrigerator to keep it cold. Roll the dough out on a floured counter to a thickness of 1/4-inch. Cut the dough into twelve 6-inch rounds. Place a round in the floured dough press. Place three tablespoons of the filling on the round and sprinkle with cheese. Close the dough press firmly to seal the edges of the pastry. Continue with the rest of the rounds and filling.
- Place the completed piroshki on a greased baking sheet. Poke a few holes in the piroshki with the tines of a fork to vent the piroshki. Brush with a beaten egg.
- Bake for 20 minutes or until they are golden brown.
Baker’s note: You can make piroshki without a dough press—a dough press  just makes it easier. Place your filling on one-half of the round, fold the other half over until the edges meet, and press the edges together with the tines of a fork. Press firmly to make sure that you have a good seal.
