Tagliatelle is a traditional type of pasta from Emilia-Romagna and Marche, regions of Italy. Individual pieces of tagliatelle are long, flat ribbons that are similar in shape to fettuccine and are typically about 6.5 mm to 10 mm (0.25 to 0.375 inch) wide. Tagliatelle can be served with a variety of sauces, though the classic is a meat sauce or Bolognese sauce. Tagliatelle are made with egg pasta. The traditional ratio is one egg to one hundred grams of flour.
