Wash and cook the beets. After cooking, peel off the peel and roughly grate the tubers on a kitchen grater (attention: put on rubber gloves if you don`t like pink hands ).
Cut the pork belly into small cubes and fry together with the diced onions in a large saucepan. Deglaze with the vegetable stock and add the grated beetroot. If necessary, a little more water can be added, depending on how thick the soup is now.
Now season with the specified spices. Mix the sour cream with a small amount of the hot soup in a separate bowl, then add to the soup (this will prevent the cream from curdling).
Now maybe season with a little lemon juice (approx. 1 teaspoon) - not too much so that it doesn`t get too sour. The soup is really seasoned when you don`t want to stop trying. To do this, boil boiled potatoes, distribute them on the plates and pour the soup over them.
