Cook chitarra pasta or spaghetti according to package directions. Do not rinse pasta with cold water.

In a large skillet, heat the olive oil, and add the crushed garlic. Heat the garlic in the oil for a few seconds to infuse the flavor of the garlic in the oil. Remove the garlic, and set aside.

Add the porcini mushrooms to the skillet, and cook for approximately 5 minutes, or until tender. Add the heavy cream, truffle paste, pepper, and cook for 2 minutes. Add the cooked pasta to the skillet and mix all ingredients together.

To serve, plate pasta, and sprinkle with grated Parmesan.
