Nina's Russian Cold Beet Soup (Kholdnyk)
Feel adventuresome? Use fresh beets with tops. Clean and cook beets and tops on stove top in water until tender. Save and use the broth (strained) that is produced. Chill, and in place of canned beets add fresh along with the tops.
One 16 ounce container of light sour cream and 16 oz. cold water can substitute for buttermilk or yogurt -- both work very well with the same amounts being used as the light sour cream. Basically use equal amount of yogurt or light sour cream and cold water to equal 1 quart of total liquid.
