- ¼ of a black truffle, peeled or shaved
- 1 TB truffle oil
- ½ lb ricotta cheese
- ¼ lb parmesan
- ¼ lb mascarpone
- salt to taste
Combine all ingredients in a standing mixer or large bowl and combine. Once fully combined, scoop into piping bag and reserve until ready to form the pasta.
• 1 3/4 cups (or 8 ounces) all-purpose flour
• 6 large egg yolks
• 1 large whole egg
• 1 1/2 tsp olive oil
• 1 TB milk
Mound the flour on a board or other surface and create a well in the center, pushing the flour to all sides to make a ring with sides about 1 inch wide. Make sure that the well is wide enough to hold all the eggs without spilling.
Pour the egg yolks, egg, oil, and milk into the well. Use your fingers to break the eggs up. Still using your fingers, begin turning the eggs in a circular motion, keeping them within the well and not allowing them to spill over the sides. This circular motion allows the eggs to gradually pull in flour from the sides of the well; it is important that the flour not be incorporated too rapidly, or your dough will be lumpy. Keep moving the eggs while slowly incorporating the flour. Using a pastry scraper, occasionally push the flour toward the eggs; the flour should be moved only enough to maintain the gradual incorporation of the flour, and the eggs should continue to be contained within the well. The mixture will thicken and eventually get too tight to keep turning with your fingers.
When the dough begins thickening and starts lifting itself from the board, begin incorporating the remaining flour with the pastry scraper by lifting the flour up and over the dough that's beginning to form and cutting it into the dough. When the remaining flour from the sides of the well has been cut into the dough, the dough will still look shaggy. Bring the dough together with the palms of your hands and form it into a ball. It will look flaky but will hold together.
Knead the dough by pressing it, bit by bit, in a forward motion with the heels of your hands rather than folding it over on itself as you would with a bread dough. Re-form the dough into a ball and repeat the process several times. The dough should feel moist but not sticky. Let the dough rest for a few minutes while you clean the work surface.
Dust the clean work surface with a little flour. Knead the dough by pushing against it in a forward motion with the heels of your hands. Form the dough into a ball again and knead it again. Keep kneading in this forward motion until the dough becomes silky-smooth. The dough is ready when you can pull your finger through it and the dough wants to snap back into place. The kneading process can take anywhere from 10 to 15 minutes. Even if you think you are finished kneading, knead it for an extra ten minutes; you cannot overknead this dough. It is important to work the dough long enough to pass the pull test; otherwise, when it rests, it will collapse.
Double-wrap the dough in plastic wrap to ensure that it does not dry out. Let the dough rest for at least 30 minutes and up to 1 hour before rolling it through a pasta machine. The dough can be made a day ahead, wrapped and refrigerated; bring to room temperature before proceeding.
To form sheets for agnolotti, use 1/2 of the recipe pasta dough, divided again into two or three pieces. Run the dough through a pasta machine as for ravioli. The size will vary according to the pasta machine used, but the sheets should be at least five inches wide. It is important that your pasta sheet be thin enough so that you can see your fingers through it, but not so thin that it's translucent. Keep the pasta sheets covered, as they dry out quickly, and proceed with filling the agnolotti.
To fill agnolotti:
If you are planning on using the agnolotti immediately, have a large pot of lightly salted boiling water ready. Work with one sheet of pasta at a time, keeping the remaining sheets covered. Work quickly, as fresh pasta will dry out.
Lay the pasta sheet on a lightly floured surface with a long side facing you. Trim the edges so they are straight. Place the agnolotti filling in a pastry bag fitted with a 1/2-inch plain tip. Pipe a "tube" of filling across the bottom of the pasta sheet, leaving a 3/4-inch border of pasta along the left, right and bottom edges.
Pull the bottom edge of the pasta up and over the filling. Seal the agnolotti by carefully molding the pasta over the filling and pressing lightly with your index finger to seal the edge of the dough to the pasta sheet; don't drag your finger along the dough to seal, or you risk ripping the dough.
When it is sealed, there should be about 1/2 inch of excess dough visible along the tube of filling (where you sealed it). Be certain that you are sealing tightly while pressing out any pockets of air. Seal the left and right ends of the dough.
Starting at one end, place the thumb and forefinger of each hand together as if you were going to pinch something and, leaving about 1 inch of space between your hands and holding your fingers vertically, pinch the filling in 1-inch increments, making about 3/4 inch of "pinched" are between each pocket of filling. It is important to leave this much "pinched" area between the agnolotti, or when the agnolotti are separated, they may come unsealed.
Run a crimped pastry wheel along the top edge of the folded-over dough, separating the strip of filled pockets from the remainder of the pasta sheet. Don't cut too close to the filling, or you risk breaking the seal. Separate the individual agnolotti by cutting the center of each pinched area, rolling the pastry wheel away from you. Working quickly, place the agnolotti on a baking sheet dusted with a thin layer of cornmeal, which will help prevent sticking. Don't let the agnolotti touch each other, or they may stick together.
Repeat the same procedure on the remainder of your pasta sheets. Either cook the agnolotti immediately in the boiling water, or place the baking sheet in the freezer. Once the agnolotti are frozen, place them in airtight freezer bags and keep them frozen for up to several weeks. Cook the agnolotti while still frozen.
To plate, toss in butter and finish with more truffle shavings and grated parmesan cheese.
