It's definitely the taste of the white truffle that makes this dish so special. A must for truffle lovers!
Put a pan of water on to boil. Add salt when it starts to boil and bring to the boil again. Cook the tagliolini as per the instructions on the packet until they are 'al dente'. Save some of the cooking water before draining.
Add the cooked pasta to the butter, sprinkle with some grated Parmesan and cook over a gentle heat for a minute whilst stirring the pasta to coat it with the sauce.
Divide the pasta among 4 warmed plates, sprinkle a little more Parmesan onto the pasta and finally shave the remaining truffle over the top of the dish.
In order to shave the truffle correctly you will need to have a special tool called a truffle/chocolate shaver. These are quite easy to find and can also be ordered online form Amazon.
