Spaghetti is a long and thin pasta originating from Italy. Traditional spaghetti is made using durum wheat semolina and water. The pasta was originally made in 50cm lengths but as it gained popularity the length of the pasta decreased in size. Today, spaghetti is most commonly available in 25–30cm lengths. A variety of pasta dishes are made using spaghetti such as spaghetti alla Carbonara and spaghetti Bolognese.
