Arrange all products conveniently. Prepare a pot, pan and mold. Rinse the millet thoroughly. Turn on the oven to preheat to 250˚C. Wash and peel vegetables and mushrooms.
Take care of mushrooms. Coarsely chop the champignons and place in a saucepan. Add salt and cook for about 20 minutes. Then turn off the heat and leave the mushrooms in the broth.
Prepare the roast. Coarsely chop the onion and carrots and place in a preheated frying pan with vegetable oil. Fry until half cooked, about 5-7 minutes.
Combine products. Cut the potatoes into pieces. Take a cauldron, put fried vegetables, millet, potatoes in it and fill it with mushrooms and broth. Calculate so that per 100 g of millet there is 1 liter of water.
Proceed to the final stage of preparing kulesh. Place the cauldron with kulesh in an oven preheated to 250˚C for 1 hour. Once the contents boil, reduce the temperature to 160˚C. Make sure that it does not boil, but simmers in the oven.
For a spectacular serving, pour lean kulesh into a tureen and sprinkle with chopped herbs. Serve with lean mayonnaise.
