All you'll need is a metal kitchen appliance with holes. Then, a colander or cheese grater will do the trick. Some individuals enjoy making a thick dough and grating it through a cheese grater's holes.  However,  when using a spaetzle maker, you will maintain the spaetzle batter as liquid as cake batter, and you'll be able to swiftly push it through a spaetzle maker into a pot of boiling water assuring a higher-quality result.
