# How to Make It:
01 - Mix flour and salt in a large bowl. Create a well in the center, add egg, melted butter, sour cream, and water. Stir to combine, then knead on a floured surface for 5 to 7 minutes until smooth and elastic. Cover with a damp towel and let rest for 30 minutes.
02 - Boil potatoes in salted water until tender, about 15 to 18 minutes. Drain and mash until smooth. Melt 2 tablespoons butter in a skillet over medium heat. Sauté finely chopped onion until golden, about 5 minutes. Combine mashed potatoes, sautéed onion, farmers cheese, and cheddar. Season with salt and pepper. Let cool.
03 - Roll out dough on a floured surface to approximately 1/8 inch thickness. Cut into 3-inch circles. Place a heaping teaspoon of filling in the center of each circle. Fold in half and pinch edges to seal. Place assembled dumplings under a towel to prevent drying.
04 - Bring a large pot of salted water to a gentle boil. Cook dumplings in batches; once they float to the surface, continue cooking for 1 to 2 minutes. Remove with a slotted spoon.
05 - Melt 3 tablespoons butter in a large skillet over medium-low heat. Add sliced onions and cook slowly, stirring frequently, until deeply golden and sweet, about 20 to 25 minutes.
06 - In the same skillet, add boiled dumplings in batches. Fry on both sides until golden and crisp, about 2 to 3 minutes per side.
07 - Serve hot, topped with caramelized onions, a dollop of sour cream, and chopped chives or parsley if desired.
