In a large saute pan, over medium heat, cook bacon until crispy. Reserve bacon in pan with rendered fat.
In a large bowl, mix flour, salt, pepper, nutmeg, cayenne and baking powder to combine. Beat eggs and milk together in a small bowl and stir into dry mixture until smooth and uniform.
Bring 6 cups salted water to a boil in a large pot. Poke holes using a pointed chopstick through the bottom of the aluminum pie pan to create a disposable spaetzle maker. Push the dough through the holes into the boiling water. Stir and cook for 3 minutes, or until dumplings float. Remove dumplings and immediately toss in pan with bacon. Season, to taste, with salt and pepper and garnish with parsley. Serve immediately.
