Make pasta according to traditional well technique and roll out to thinnest setting. Assemble filling by mixing blaukraut, marjoram, caraway and egg together. Lay pasta out and cut into 2-inch squares. Place 1 teaspoon filling on each square and fold each tortelloni. Continue until all pasta is used up.
To serve, bring 6 quarts water to boil and add 2 tablespoons salt. Drop turteln in water and cook until tender, about 4 to 5 minutes. Meanwhile, melt butter in a 12- to 14-inch saute pan. Drain cooked turteln well and place in pan with butter. Return to heat, add scallions and caraway, toss to coat and serve.
