In large bowl, combine the flour, salt, pepper, and nutmeg.
In another small mixing bowl whisk the eggs and milk together.
Make a well in the center of the dry ingredients and pour in the egg-milk mixture.
Gradually draw in the flour from the sides and combine well: the dough should be smooth and thick.
Let the dough rest for 10 - 15 minutes.
Bring 3 quarts of salted water to boil in a large pot, then reduce to simmer.
To form the spaetzle, hold a large holed colander or spaetzle lid over the simmering water and push the dough through the holes with a spatula.
Do this in batches so you don't overcrowd the pot. Cook for 3-4 minutes or until the spaetzle floats to the surface, stirring gently to prevent sticking.
Drain the spaetzle in a colander and rinse with cool water.
Melt the butter in a large skillet over medium heat and add the sage leaves, sauteing until butter begins to turn golden brown.
Add spaetzle and toss to coat, cooking for 1-2 minutes.
Season with salt & pepper before serving.
Garnish with crispy sage leaves.
