Scrape the batter into a colander with 1/4-inch holes. Set the colander at least 1 inch over the boiling water. Using a rubber scraper, press the batter through the holes into the boiling water. Stir the spaetzle once or twice to separate them. As the spaetzle rises to the surface, transfer them to a clean colander to drain. Shake off the excess water, transfer to a bowl and serve.
