This is potato dumplings, and depending on where in Norway we live, we have 3 different names for this dish.
"Komler", as we call it in Stavanger is served with lamb meat and/or sausage, together with mashed turnip. “Komler” are made of raw potatoes.
My late grandmother who lived further north, always called them “Klubb”
And in and around Bergen (Norways second biggest city) they call them “Raspeball”
