Potato Dumpling Soup

A now - forgotten  tradicional soup, what I don't know, where it comes from originally, but it has also become traditional in Hungary. In the time of our grandmothers, when the family was still big, there was little food, but there was plenty of potatoes, so they cooked so that the family wouldn't stay hungry. The other day, I prepared this forgotten traditional soup.

Ingredients: 500g Potato, 200g Flour, 1pcs Egg Yolk,  2tbsp Lard, 250g Chorizo, 1pcs Brown Onion, 2pcs Garlic Clove, 1tsp Ground Cumin, 1tsp Smoked Paprika, 2pcs Bay Leaves, 1pcs Carrot, 1pcs Parsnip, 2pcs Celery Stick, 100g Sour Cream, 2tsp Flour, 1tsp Vinegar, Parsley - to taste.

First make the dumplings. For this, peel the potatoes, cut them into wedges and boil them in salted water until soft, then drain them, crush them while still warm and cool them completely. When it has completely cooled, add the flour and egg yolk, sprinkle with salt and ground pepper, then knead and from balls the size of walnuts. Then set aside. For the soup, heat the lard in a large bowl and fry the diced chorizo, onion and garlic. When they are browned, add the diced or sliced vegetables, add the ground cumin, smoked paprika and bay leaf, pour 3l of water, season generously with salt and ground pepper, then cook until soft. If the vegetables have softened, you can add the pre - prepared dumplings. The dumplings will sink to the bottom of the soup, once they have come to the top of the soup, cook for another 3 - 4min. Meanwhile, mix the sour cream with the flour until smooth, then add a little of the hot soup to balance the heat and pour it into the soup. Finally season with vinegar to taste.
