Pour water into a saucepan. Heat it and put the cabbage leaves in the water for 5 minutes. This will soften the leaves and allow you to roll the filling in them.
Place the cabbage leaves in a colander or sieve, then let the excess water drain off.
While the cabbage leaves are cooling, cook the rice. Pour a large amount of water over the rice and cook until half-cooked.
Place the half-cooked rice in a colander or sieve and then let it cool slightly.
Prepare the filling. Finely chop the onion.
In a deep bowl, combine the minced meat, rice and onion. Season with salt and pepper and mix well.
Take a cabbage leaf and put some filling on it.
Wrap the cabbage leaf into an envelope.
Form the remaining cabbage rolls in this manner.
Prepare the sauce. Mix sour cream, tomato paste, flour and water.
Heat the sauce over medium heat until all the ingredients are combined and it thickens slightly. Add a pinch of salt and sugar to taste to achieve the desired taste.
Place the cabbage rolls in a saucepan and pour the sauce over them. Simmer them over low heat for an hour.
The cabbage rolls are ready. Garnish them with green onions, sour cream and a little grated cheese. Enjoy.
