Peel the onion and cut into small cubes. Remove the garlic clove from the shell and press through the press. Clean the mushrooms and cut into thin slices. Also cut the sausage into slices.
Heat the lard in a pan and sweat the mushroom and sausage slices. Then add the onion cubes and continue to fry everything. Add the cooked potatoes and the pressed garlic clove. Swirl everything and season with salt, pepper, paprika powder and caraway seeds. Mix the sour cream with the potato boiling water, add to the pan, stir and let simmer for another 2 minutes.
