Roman cuisine comes from the Italian city of Rome. It features fresh, seasonal and simply-prepared ingredients from Roman Campagna. These include: peas, globe artichokes and fava beans, shellfish, milk-fed lamb and goat, and cheeses such as Pecorino Romano and ricotta. Olive oil is used mostly to dress raw vegetables, while Strutto (pork lard) and fat from prosciutto are preferred for frying. The most popular sweets in Rome are, little individual pastries called pasticcini, gelato (ice cream) and handmade chocolates and candies.  Special dishes are often reserved for different days of the week; for example, gnocchi is eaten on Thursdays, baccalà (salted cod) on Fridays, and trippa on Saturdays.
Rome's food has evolved through centuries and periods of social, cultural, and political changes. Rome became a major gastronomical center during ancient age. Ancient Roman cuisine was highly influenced by Ancient Greek culture. Subsequently, the empire's enormous expansion exposed Romans to many new, provincial culinary habits and cooking techniques. In the beginning, the differences between social classes were not very great, but disparities developed with the empire's growth. Later, during the Renaissance, Rome became well known as a center of high-cuisine, since some of the best chefs of the time worked for the popes. An example of this could be Bartolomeo Scappi, who was a chef working for Pius IV in the Vatican kitchen, reaching fame with his cookbook Opera dell'arte del cucinare, published in 1570. Here he lists approximately 1000 recipes of Renaissance cuisine and describes cooking techniques and tools, giving the first known picture of a fork.
Traditional Cucina Romana
The Testaccio rione, Rome's trade and slaughterhouse area, is the place where Rome's most original and traditional foods can still be found. The area was often known as the "belly" or "slaughterhouse" of Rome, and was inhabited by butchers, or vaccinari. The most common or ancient Roman cuisine included the "fifth quarter". Popular foods include pig's trotters, brain, and the genitals of other animals, which were often carefully cooked and richly spiced with different savouries, spices and herbs. The old-fashioned coda alla vaccinara (oxtail cooked in the way of butchers) is still one of the city's most popular meals and is part of most of Rome's restaurants' menus. Lamb is also a very popular part of Roman cuisine, and is often roasted with spices and herbs. There is a considerable Jewish influence in Roman cuisine, since they were many in the city, and some of the traditional meals of the ghetto date back over 400 years. Such include the carciofi alla giudia (Jewish-style artichokes) and Jewish courgettes.
Pasta in Rome
Pasta is one important element of Roman cuisine. Famous pasta sauces include amatriciana, carbonara, (a sauce made with pancetta or guanciale - pig's cheek -, cheese and egg), cacio e pepe and gricia (like carbonara but without eggs). Alfredo (invented by the chef of restaurant "Alfredo alla Scrofa") is famous abroad, but not considered traditional and mostly unheard of in Rome.
