Crispy Fried Pierogi with Savory Toppings

Method

1. In a large bowl, mix flour and salt. Gradually add water, kneading until smooth. Cover and let rest for 30 minutes.
2. In a separate bowl, combine mashed potatoes, cheese, and a pinch of pepper. Mix well.
3. Roll out the dough and cut into circles. Place a spoonful of filling in the center of each circle.
4. Fold the dough over the filling, pressing the edges to seal. Pinch the edges to form a crescent shape.
5. Heat oil in a deep fryer or large pot to 350°F (175°C). Dredge the pierogi in flour, then carefully add to the hot oil.
6. Fry the pierogi until golden brown, about 2-3 minutes. Drain on paper towels.
7. In a skillet, melt butter and sauté onions until crispy. Serve the fried pierogi topped with the onions and a side of sour cream.
