Knoephla soup

Knoephla, also spelled knephla /ˈnɛflə/, is a type of dumpling, commonly used in soups in the United States. The word is related to the modern German dialect word Knöpfle, meaning little knob/button. Traditional knoephla soup is a thick chicken and potato soup, almost to the point of being a stew. It is particularly common in the U.S. states of Minnesota, South Dakota, and North Dakota, where there was significant settlement of German emigrants from the Russian Empire. There are different iterations known throughout, though the North Dakotan iteration typically contains just potatoes and dumplings.
