Kalatusha is a traditional soup originating from Polissya. The soup is usually made with a combination of mushrooms, fish such as carp, flour, butter, oil, roasted vegetables (such as beets, carrots, celery, tomatoes, onions), allspice, bay leaves, dill, parsley, salt, and pepper.

The vegetables (carrots, celery, onions, beets, and tomatoes) are roasted in the oven. The carp is cut into pieces and mixed with mushrooms, bay leaves, dill, parsley, and allspice. The mixture is cooked in order to create a broth that is then strained through a sieve.

A mixture of flour and butter is added to the broth for thickening, along with the roasted vegetables. The carrots and celery are puréed and then mixed with the broth in order to create a thick soup that's served with the mushrooms and pieces of fish on top.
