For the Fresh Pasta Dough: Place the flour on a work surface. Make a well in the center and add the eggs, olive oil and salt. Begin mixing the eggs with a fork, being careful to stay in the center. Add flour from the sides of the well little by little. When it becomes too stiff to mix with a fork, continue, incorporating flour by gently kneading the dough.
When the dough has absorbed about as much flour as it's going to, move it to another area of the counter, scrape up the remaining flour and pass it through a sifter to remove any dried bits (you don't want these in your dough.)
Then start kneading, keeping the table lightly dusted with flour. When it no longer sticks to the table, you're about finished. In the end, you want a smooth, firm but resilient, homogenous ball of dough, neither too dry nor too soft. Poke the dough and it should spring right back, press your fingers into the middle of the ball and it should feel just a bit tacky. If it is very sticky, you'll need to add more flour.
Wrap the dough loosely in plastic and let it rest for at least 1 hour. This will make it easier to roll out.
For the Mushroom Filling: Heat the oil in a frying pan add the mushrooms and saute. Add the garlic and deglaze with the white wine.
When the wine has cooked away, add the mushroom stock and simmer until almost all the liquid has evaporated.
Let the mushrooms cool then pulse in a food processor until coarsely chopped. In a mixing bowl, fold in the herbs and season with salt and pepper to taste. You can also stir in a drop of truffle oil if desired.
For the Porcini Mushroom Stock: Place porcini in a saucepot and cover with water. Bring to a boil then lower heat and simmer for 5 minutes. Remove from the heat and let the mushroom steep for 30 to 40 minutes.
Pass the stock through a strainer lined with a cheesecloth or a dampened paper towel to remove the mushrooms and any bits of sand.
You should have 4 cups of flavorful, not overly concentrated, stock.
For the Fonduta: Trim the red rind off the cheese and chop in a food processor. Put the cheese in a stainless steel mixing bowl, pour the milk over the cheese, cover with plastic wrap and refrigerate over night. Fill a saucepan halfway with water and bring to boil. Place the mixing bowl over the pot to create a double boiler and allow the cheese to dissolve slowly into the milk, whisking occasionally.
When the milk and cheese are completely amalgamated, stir in the flour. Whisk in the egg yolks one at a time. When all the eggs have been incorporated continue whisking over the heat until the mixture is thick and creamy and warm to the touch. Be careful not to let the fonduta get to hot or it will curdle.
For the Ravioli: Using a pasta rolling machine or rolling pin, roll pasta out into a very thin sheet 6 to 8 inches wide. Spoon the mushroom filling on to half of the sheet in 2 rows of even rounds. Make a small indentation in the center of each mound and, with a pastry bag or small spoon, place a little of the fonduta into the center of each mound. Brush a little of the egg yolk around the mushroom filling then carefully lay the other half of the pasta sheet over the top. Gently press around the filling. Using a scalloped pastry wheel, cut the pasta in between the mounds to form individual ravioli. Keep the ravioli on a board or pan sprinkled with flour until ready to cook. (May be made and kept in refrigerator up to a day in advance). Bring a pot of salted water to a boil add the ravioli and cook 3 to 5 minutes; when the pasta rises to the surface they are done. Melt the butter in a saucepan. Add the asparagus, a pinch of salt. Add the ravioli, toss with the Parmigiano cheese and serve.
