A Spaetzle Slide makes roundish balls. An extruder such as a potato ricer (with holes on underside only preferred) makes long noodle shapes.
Here is a typical spaetzle recipe:
2 eggs, 2.5 cups all purpose flour, 0.5 cup milk, 0.5 cup water, 0.25 tsp salt, 0.5 cup butter
Beat eggs lightly and add milk and water. Place sifted flour and salt in a bowl and gradually stir in the egg mixture until the right consistency has been reached. Add more flour if a stiffer dough is desired. Bring about 4 qts. of salted water to a rapid boil, and you are ready to drop in the spaetzle dough. Cook for about a minute, stirring constantly. Strain and remove excess water by transferring to a paper towel. Toss with melted butter before serving.
