... while we fry in vegetable oil grated carrots and chopped onion.

Place browned vegetables in pots.

Separately mix the sour cream with water (I have 3 of the pot 2-3 tablespoons of sour cream and somewhere in 250-300 ml of water). Add salt, spices. Stir and pour in the dumplings, but not completely. Approximately as on a photo. You can add a little dried herbs. Stir, close the pot with dumplings lids and put in cold oven, turn it to 200 degrees and leave for 25 minutes.

Then remove the lid, sprinkle with cheese and open pots of dumplings put another 10 minutes in the oven.
