Rinse the pork under cold water and pat dry. Rinse the rice well until the water runs clear. Peel and rinse the onions and garlic cloves. Cut the onion into small cubes. Finely chop the garlic or pass through a press. Soak green onions and cilantro for 10 minutes in cold water, then shake off the moisture and finely chop the greens. Wash the chicken egg with soap or soda.
Prepare minced meat for hedgehogs. Cut the pork into large pieces and grind through a meat grinder or grind in a blender. In a deep bowl, mix minced pork and raw rice, beat in the chicken egg. Add salt, ground black pepper and knead the minced meat for 10 minutes.
Prepare the roast. Heat vegetable oil in a frying pan. Fry the onions, stirring, for 3-4 minutes. Then add two crushed cloves of garlic and fry for another 1-2 minutes.
Prepare sour cream sauce. In a small bowl, combine sour cream, minced garlic clove, salt and nutmeg. Add flour, chopped cilantro and green onions. Pour the sour cream sauce into a frying pan with onions and garlic, pour in 1.5 cups of water and mix well.
Put out the hedgehogs. Form small balls with a diameter of about 4-5 cm from the minced meat with rice. Place them in a frying pan with onions and sour cream sauce and pour the sauce over them well. Cover the pan with a lid and simmer the hedgehogs over low heat for 30-35 minutes until cooked.
Serve the hedgehogs in sour cream sauce hot along with a side dish of boiled buckwheat.
