In a medium bowl, mix together the all-purpose flour, salt and nutmeg. In another bowl, whisk together the eggs and milk.
Add the egg/milk mixture and mix until the dough is just combined.
Bring a large pot of salted water to a boil. Place spaetzle maker or metal grader over boiling water. Press dough through and boil for 2-3 minutes or until spaetzle is tender and starting to float. Remove with slotted spoon and toss with butter and some fresh parsley.
Notes
The wetter the spaetzle dough, the more delicate it will be, but you also want it to be thick enough to hold its shape. The dough should resemble thick pancake batter.
Oil your spaetzle maker or whatever device you are using to make the spaetzle so the dough won't stick to the holes.
If making a large amount of spaetzle, work in batches so there is one layer to prevent clumping.
If you are short on time, you can boil the spaetzle the day before and just sauté the day of serving.
