The dish was heavily influenced by both Chinese and French cooking. Rice noodle and spices were imported from China; the French popularized the eating of red meat.The origins of Pho as a Northern dish that spread South explains the key differences between the Northern and Southern variations. Northern style Pho tends to be simpler and is made with less ingredients. There are fewer cuts of meat and small slices of ginger are laid on top of the soup. The Pho is served without bean sprouts or herbs. Instead, it is accompanied by green chilies and lime only. Southern style Pho is a complex dish made from a dozen ingredients. Bean sprouts, fresh basil and saw herb are typically served with each bowl. As with the Northern style Pho, green chilies and lime are used as condiments.
