For the potato dumpling soup, boil the peeled and diced potatoes in 1.2 l of salted water until soft. Strain, keeping the cooking water and mash potatoes while still hot.
Finely chop peeled onions and garlic cloves, lightly fry in oil and add cumin. Remove from heat and add paprika (sweet).
Cover with cooking water, add salt, vegetables and cook until done. Mix potatoes, salt, butter and flour, knead into a smooth dough. (Cook a small test dumpling. If the dough is too soft, add some flour).
With moistened hands, form small dumplings and finish cooking in the soup. The dumplings are done when they float to the top. Sprinkle with lots of parsley before serving.
