Roman cuisine
Roman cuisine comes from the Italian city of Rome. It features fresh, seasonal and simply-prepared ingredients from the 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 small 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. History. Rome's food has evolved through centuries and periods of social, cultural, and political changes. Rome became a major gastronomical center during the ancient age. Ancient Roman cuisine was mainly based on cereals, cheeses, legumes and fruit. 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 Italian 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. Roman and all Italian cuisine were transformationally influenced by the introduction of new world crops by the Spanish, especially the tomato. 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 many Jews lived 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 Roman pasta dishes include "cacio e pepe" (cheese and black pepper), "gricia" (a sauce made with "pancetta" or "guanciale  and hard cheese, typically Pecorino Romano), carbonara" (like "gricia" but with the addition of egg), and "amatriciana" (like "gricia" but with the addition of tomato and possibly onion). "Alfredo" (invented in Rome by the chef of restaurant "Alfredo alla Scrofa") is famous abroad, but not considered traditional and mostly unheard of in Rome. There used to be a pasta museum in Rome called the Museo Nazionale della Paste Alimentari (the National Museum of Pasta), but now there is a hotel there. Rome's most common pasta shape is spaghetti, but there are many other forms. Beverages. The city is known  as a center of white wine. Frascati and Castelli Romani have been called the best ones in the city. Other elements of Roman food. There are also many other dishes in Roman cuisine, including several desserts and sweets, many of which are made with ricotta cheese. Typical of Rome is the "grattachecca".
