1. Making the Pasta Dough

Start by placing the flour on a clean surface, forming a well in the center. Crack the eggs and extra yolk into the well, then slowly mix them with the flour using a fork. As the mixture thickens, begin kneading it by hand. Knead the dough for about 10 minutes until it becomes smooth and elastic. Wrap it in plastic wrap and let it rest at room temperature for one hour. Resting allows the gluten to relax, making it easier to roll out later.

2. Preparing the Crab Filling

While the dough is resting, prepare the filling. In a medium bowl, combine the crab meat, ricotta cheese, lemon juice, parsley, and salt. Stir well until fully incorporated. Place the mixture in the refrigerator to chill. This step is important because a cold filling is easier to handle and prevents it from becoming too soft when assembling the ravioli.

3. Rolling Out the Pasta Dough

After the dough has rested, divide it into two equal portions. Lightly flour a clean surface and roll out each piece of dough into thin sheets. The pasta should be nearly see-through—this ensures a delicate texture when cooked. If using a pasta machine, start on the widest setting and gradually work down to the thinnest setting for the best results.

4. Filling and Shaping the Ravioli

Take one sheet of rolled-out pasta and place small portions of the crab filling onto it, leaving about one inch of space between each mound. Carefully place the second sheet of pasta over the top and press around each mound to seal the edges. Use a ravioli cutter or a sharp knife to cut the ravioli into 2×2-inch squares. Press the edges firmly to prevent any filling from leaking during cooking.

5. Cooking the Ravioli

Bring a large pot of salted water to a gentle boil. Carefully drop the ravioli into the water and cook for about three minutes or until they float to the surface. Avoid rapid boiling, as this can cause the ravioli to break apart. Once cooked, remove them with a slotted spoon and set them aside.

6. Finishing with Butter Sauce

In a small pan, melt the butter over low heat until it becomes golden and slightly nutty in aroma. Drizzle it over the cooked ravioli just before serving. This simple butter sauce enhances the flavors without overpowering the delicate crab filling.
