2 ½ cups all-purpose flour
1 pinch salt
½ cup milk
2 large eggs, beaten
1 tablespoon unsalted butter
1 (32 fluid ounce) container chicken stock, or as needed
Stir flour and salt together in a large bowl. Add milk, beaten eggs, and butter. Knead dough until smooth, about 5 minutes. Let rest in a covered bowl for 10 minutes.
Roll dough out on a floured surface to 1/8 or 1/4 inch thickness. Cut into desired lengths and shapes. Allow to air dry before cooking, at least 1 hour.
Bring chicken stock to a boil in a large pot. Add noodles; cook at a boil until noodles are salt with no bite and the broth has thickened, about 15 minutes.
