Fettuccine is a type of pasta that is characterized by its long, flat, and wide ribbons. This pasta is traditionally made from egg and flour, giving it a slightly rich and soft texture compared to other pasta varieties like spaghetti or penne. Fettuccine is typically about 1/4 inch (6 mm) wide, making it a perfect choice for hearty sauces, such as Alfredo or Bolognese, because the wide noodles can hold onto thick, creamy, or meaty sauces. It is often served fresh or dried, and its texture can vary slightly depending on whether it's homemade or commercially produced. The versatility and richness of fettuccine make it a beloved pasta in many Italian and international dishes.
