01 - Mound the flour on a clean work surface and create a deep well in the center. Crack the eggs into the well and add the salt. Using a fork, gently beat the eggs while gradually drawing in flour from the inner walls of the well. Continue mixing until a shaggy dough forms, then knead firmly for 7 to 8 minutes until the dough is silky smooth and springs back when pressed. Wrap tightly in plastic wrap and let rest at room temperature for 20 minutes.
02 - In a mixing bowl, combine the finely chopped cooked chicken breast, ricotta cheese, grated Parmesan, minced garlic, chopped parsley, nutmeg, and a generous pinch each of salt and pepper. Stir thoroughly until all ingredients are evenly distributed and the mixture holds together when pressed.
03 - Unwrap the rested dough and divide it into manageable portions. Roll each portion out on a lightly floured surface to approximately 1/16 inch thickness. Cut the sheet into 2-inch squares or rounds using a knife or pasta cutter. Place roughly 1 teaspoon of filling in the center of each piece. Fold the dough over the filling to form a half-moon, pressing out any air and sealing the edges firmly. Bring the two bottom corners together and pinch to form the classic tortellini shape. Transfer finished tortellini to a semolina-dusted baking sheet.
04 - Bring a large pot of generously salted water to a rolling boil. Carefully drop the tortellini in batches to avoid crowding. Cook for 3 to 4 minutes, or until each piece floats to the surface and the pasta edges are tender. Remove with a slotted spoon and set aside briefly.
05 - While the tortellini cooks, melt the butter in a saucepan over medium heat. Pour in the heavy cream and bring to a gentle simmer for 2 to 3 minutes, allowing it to thicken slightly. Stir in the Parmesan cheese until fully melted and the sauce is smooth. Season generously with freshly ground black pepper.
06 - Gently toss the cooked tortellini in the cream sauce until evenly coated. Divide among warm plates and finish with an extra sprinkle of Parmesan cheese and chopped fresh parsley.
