Pasta is a staple food of traditional Italian cuisine, now of worldwide renown. It takes the form of unleavened dough, made in Italy, mostly ofdurum wheat (more rarely buckwheat flour), water and sometimes eggs. Pasta comes in a variety of different shapes that serve for both decoration and to act as a carrier for the different types of sauce. Pasta also includes varieties, such as ravioli and tortellini, that are filled with other ingredients, such as ground meat or cheese. Pasta is eaten in Italy only as first course or nowadays as “piatto unico”.
