MASHED POTATO PIEROGI RECIPES

Steps:

• Make the dough: In a medium bowl, whisk egg. Add sour cream, and whisk until smooth. Add milk and 1 cup water, and whisk until combined. Slowly add about 3 cups flour, and stir with a wooden spoon to combine.
• Turn dough out onto a well-floured surface and work in about 1 cup flour as you knead. Use a plastic scraper to lift dough as it will stick to the counter before flour is worked in. Continue kneading for 8 to 10 minutes, working in another 1/2 cup flour. The dough should be elastic in texture and no longer sticky. Be careful not to add too much flour, as this will toughen dough. Place dough in a lightly floured bowl and cover with plastic wrap and let rest while you prepare filling.
• Make the filling: Place potatoes in a large pot, and cover with cold water. Add salt. Place over high heat, and bring to a boil. Cook until fork-tender. Drain and mash with a potato masher. Add 4 tablespoons melted butter and the cheeses, and continue to mash until well incorporated. Season with salt and pepper to taste. Place a large pot of salted water over high heat, and bring to a boil. Lay a clean linen towel on your counter, and evenly distribute cornmeal on it to prevent sticking.
• On a floured surface, roll out dough to about 1/8 inch thick. Using a glass or cookie cutter measuring 2 1/2 inches in diameter, cut out as many circles as possible. Gather dough scraps together, rolling them out again, and continue cutting.
• Form filling into 1 1/2-inch balls, and place a ball in the center of each dough circle. Holding a circle in your hand, fold dough over filling, and pinch the edges, forming a well-sealed crescent. Transfer to linen towel. Continue this process until all dough circles are filled.
• Place pierogi in boiling water in batches. They will sink to the bottom of the pot and then rise to the top. Once they rise, let them cook for about a minute more. Meanwhile, drizzle platter with remaining 8 tablespoons melted butter. Remove pierogi from pot, and transfer to platter to prevent sticking. Serve immediately.
