In a large pot of cold water (or vegetable stock for a richer taste), boil all the ingredients slowly for about an hour (until vegetables are all tender).
Blend the cooked beets and carrots (in a blender or with an electric hand blender) and return them to the pot. Add the citric acid and sugar one teaspoon at a time. Taste after each teaspoon of citric acid and sugar until you have the right balance of sweet and sour.
Serve hot or cold, with a large dollop of sour cream.
