Bring a large pot of salted water to a full boil. Dip a large clean spoon into the water and then drop a large spoonful of dough into the water. Dipping the spoon into the boiling water before each spoonful of dough helps keep the dough from sticking onto the spoon.
When all dumplings are in the water, cover loosely and cook 20 minutes stirring occasionally.
Drain, place in a serving dish and add melted butter. Toss to coat.
