SOUR CREAM PIEROGI DOUGH RECIPES

Steps:

• Tip four cups of flour onto your work surface, make a shallow well.
• Add sour cream in. Mix until combined - with your hands or with an electric mixer.
• If the dough feels too sticky to handle, add more flour.
• Dust both hands with flour and start kneading to form the dough.  
• Cover the dough with a cloth or a large bowl. Set aside for 20-30 minutes. You can let the dough rest longer, even up to a few hours.
• Dust the worktop with some extra flour and transfer the dough onto it. Knead the dough for a minute or two. Cut a smaller piece of the dough off and roll it out - the thinner, the better. 
• Cut out the circles - I use a rim of a glass, but a round cookie cutter works too. The size is up to you, but roughly 3 inches (8 cm) seems optimal.
• Scoop 1 tablespoon of pierogi filling of your choice and place it in the center of each circle. 
• Press the edges and seal each dumpling.
• Bring a large pot of water to boil, then reduce the heat to medium. Drop in pierogi in small batches, a few at the time. Wait for them to float, once they do - continue cooking for another minute. Remove them with a slotted spoon onto a plate.
• Continue until you’re out of pierogi.
• Serve with melted butter or another topping of your choice. 
• If you prefer a crispier skin, melt some butter on a frying pan. Fry dumplings on both sides until golden.

Steps:

• In a large bowl, stir together the flour and salt. In a separate bowl, whisk together the butter, sour cream, eggs, egg yolk and oil. Stir the wet ingredients into the flour until well blended. Cover the bowl with a towel, and let stand for 15 to 20 minutes.
• Place potatoes into a pot, and fill with enough water to cover. Bring to a boil, and cook until tender, about 15 minutes. Drain, and mash with shredded cheese and cheese sauce while still hot. Season with onion salt, salt and pepper. Set aside to cool.
• Separate the perogie dough into two balls. Roll out one piece at a time on a lightly floured surface until it is thin enough to work with, but not too thin so that it tears. Cut into circles using a cookie cutter, perogie cutter, or a glass. Brush a little water around the edges of the circles, and spoon some filling into the center. Fold the circles over into half-circles, and press to seal the edges. Place perogies on a cookie sheet, and freeze. Once frozen, transfer to freezer storage bags or containers.
• To cook perogies: Bring a large pot of lightly salted water to a boil. Drop perogies in one at a time. They are done when they float to the top. Do not boil too long, or they will be soggy! Remove with a slotted spoon.
