Make a dough from flour, eggs, salt and water (enough to achieve the desired consistency) and let it rest for about 15 minutes. Scrape the dough into a pot of boiling water, bring to the boil briefly and drain. Quench the finished spaetzle and then let it dry well. Wash, cut eighth, core and slice apples. Heat the butter in a pan and sauté the apple slices. Add the spaetzle and lightly roast everything together for about 10 minutes.
Care for the apple spaetzle with sugar and cinnamon and serve.
