14 - 3 tablespoons unsalted butter

# How-To:
01 - Combine flour and salt in a large bowl. Create a well and add egg, melted butter, sour cream, and lukewarm 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. In a skillet, melt 2 tablespoons butter over medium heat and sauté chopped onion until golden, approximately 5 minutes. Mix mashed potatoes, sautéed onion, farmer's cheese, and cheddar. Season with salt and pepper, then let cool.
03 - Roll dough on a floured surface to ⅛-inch thickness. Cut into 3-inch circles. Place one heaping teaspoon of filling in the center of each circle. Fold dough in half and pinch edges to seal. Keep dumplings covered with a towel to prevent drying.
04 - Bring a large pot of salted water to a gentle boil. Cook dumplings in batches; once they float, cook an additional 1 to 2 minutes. Remove with a slotted spoon.
05 - In a skillet, melt 3 tablespoons butter over medium-low heat. Add sliced onions and cook slowly, stirring frequently, until deep golden and sweet, about 20 to 25 minutes.
06 - Using the same skillet, pan-fry boiled dumplings in batches until golden and crisp on both sides, about 2 to 3 minutes per side.
07 - Serve dumplings hot, topped with caramelized onions, a dollop of sour cream, and chopped chives or parsley if desired.
