This dish is easier than you think to make. It is worth the effort to see the smiles it will bring to your table. I know you will make it again. The filling for the ravioli is the way my Dad liked his ravioli. This is for you Dad.
Sift the flour onto a board or counter top. Make a well in the center and add 3 egg yolks. Add a dash of salt and 3 tablespoons of water. Combine into the flour and continue to knead the dough until a firm dough is formed, adding a little more water as needed to the dough. Cover the dough and let it stand for at least 15 minutes.
Divide the dough in half and roll out one of the halves as thin as possible.
In a mixing bowl combine the remaining 3 egg yolks, orange zest, sugar, parsley, nutmeg and Romano cheese. Place a teaspoon of the mixture on the center of the dough; repeat spacing teaspoonfuls about 2 inches apart.
Roll out the remaining dough and carefully position it as a top layer, brushing the edges lightly with water to seal the layers. Press the 2 layers of dough together around the edge mound of the cheese mixture.
Cut into squares with a pastry wheel or a sharp knife. Press the edges down with a fork. Drop into boiling salted water. Simmer for about 10 minutes. The ravioli will float to the top. Drain Well!
