What is "knoephla"

Knoephla, also spelled knephla , is a type of dumpling, commonly used in soups. 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.
