Yield: 1 1/2 quarts
Roll the pasta dough out on a pasta machine down to the thinnest setting, and cut 3-inch squares from the dough. Place a scant tablespoon of the filling in the middle of 1/2 of the squares, and top them with the other squares, pressing the edges together to seal. Set aside.
Bring 6 quarts of water to a boil and add 2 tablespoons salt. Cook the ravioli in the boiling water until they are tender and cooked through, about 5 to 7 minutes.
Meanwhile, place the chicken stock, sage, and butter into a 12 to 14-inch saute pan, and bring to a boil. Drain the pasta and toss into the pan with the butter mixture. Toss over high heat, season with salt and pepper, and serve.
As you expand the well, keep pushing the flour up from the base of the mound to retain the well shape. The dough will come together when half of the flour is incorporated.
Start kneading the dough with both hands, using the palms of your hands. Once you have a cohesive mass, remove the dough from the board, and scrape up and discard any leftover bits. Lightly reflour the board and continue kneading for 6 more minutes. The dough should be elastic and a little sticky. Wrap the dough in plastic and allow to rest for 30 minutes at room temperature.
Roll the pasta out on a pasta rolling machine to the desired thickness.
