My Grandmother used to make them years ago and I am looking for the correct spelling so I can search for a recipe. If it helps, she was German so that might be a German dish. Thanks! You also had to scrape the marrow out of beef bones and add it to them. Saltine crackers were also crushed and mixed with the marrow, helping to form the ball.

I haven't heard of marclaises...but these might be what your looking for. I never had very good luck with them,and there so easy..... German Noodle Dumplings (Spaetzle) Spaetzle is a very popular side dish in Germany which is surprisingly almost never offered in the U.S. A delicious part of a evening's hearty meal, it pairs well with any meat, but is especially nice with sauerbraten. While spaetzle looks more like scrambled noodles, the preparations are similar to those of dumplings. This recipe is an easy one to try. 1 cup flour 1/4 cup milk 2 eggs, beaten 1 1/2 teaspoons salt black pepper 2 quarts water (chicken or beef broth can be substituted) 2 tablespoons butter, melted toasted bread crumbs or grated cheese (optional) Mix flour, milk, eggs, 1/2 teaspoon salt and the pepper into a thick batter. In a large covered pot, heat water with the remaining 1 teaspoon salt to boiling. Holding a colander with large holes over the boiling water, press a few tablespoons at a time of the batter through the colander into the water. Stir the water once or twice to prevent sticking. When the dumplings are done, in about five minutes, they will rise to the surface and should be tender. Drain, place into a pre-warmed bowl and pour the melted butter on top. If desired, toss with the bread crumbs or grated cheese.........or add to chicken soup.

I know you said "not matzo" .. but .. German cooking actually commonly uses matzo meal to make dumplings, and I think that is really what you are looking for. In the German language, suppe mit Klöße (or Klosse) means "soup with dumplings" which were traditionally matzo balls. "Mit klosse" sounds very similar to your word "marclaises" so I think this is what you are looking for.
