Spaghetti is typically made from durum wheat semolina and water, although variations made from other grains such as whole wheat or rice flour also exist. It is commonly served with a variety of sauces, including tomato-based marinara or Bolognese sauce, creamy Alfredo sauce, pesto, or garlic and olive oil.
