Kletski (клецкі)

Instructions

1. Mix the mashed potato, still warm, with the flour, egg and salt until you have a smooth dough.
2. Sauté the chopped onion in a pan with a little oil, then add the minced meat and season with pepper.
3. Cook the meat for 8 minutes, stirring, until well browned, then let it cool.
4. Take a small piece of dough, flatten it in your hand and place a spoonful of filling in the centre.
5. Close the dough into a ball, pinching the edges well so the filling doesn't escape.
6. Drop the kletski into boiling salted water and poach for 15 minutes at a gentle simmer, then drain and serve with melted butter and sour cream.
