These delightful tagliatelle ribbons are flavoured with the unforgettable scent of truffles and the high percentage of eggs used in the making enhances this truffle flavour. A mouthful of this pasta will transport you to Italy with its heady, richness and delicious sophistication. Cook the pasta in well seasoned water for four to five minutes until it is al dente. Melt a couple of generous knobs of good quality butter in a separate saucepan. Drain the pasta and return it to the saucepan with butter. Finish with grated Parmesan and a couple of drops of truffle oil.
