Place flour in a bowl, add boiling water and blend. Knead for 5 min. Then mold dumplings into any form you wish (about 1/2" thick). Set aside.
Saute the cabbage. Add enough stock to cover it and bring to a boil. Cover pot and simmer til cabbage is tender. Add remainder of stock, bring soup to boil and drop dumplings into the soup. When dumplings rise to the surface they are cooked. Reduce flame. Place miso in bowl, add 1/4 cup broth and puree. Add puree to soup and allow to simmer for a few minutes. Garnish with parsley.
