The name "Luo Song" is said to be the Chinese transliteration of Russian "Tang" (Luo Song is Russian, from early Shanghai Pidgin English, and its pronunciation is [lê só? 】), Luo Songtang is another commonly used name. In some areas of northeast China, Luo Songtang is also called "Supo Soup".
Luo Songtang's culture:
During the October Revolution, a large number of Russians came to Shanghai. They brought vodka and Russian western food. The first western food club in Shanghai was opened by Russians. This soup evolved from Russian red vegetable soup. This soup is hot and sour, not sweet. Shanghai people are not used to it. Later, influenced by the purchase of raw materials and local tastes, it gradually formed a unique Shanghai style.
Shanghai Luo Songtang is not only suitable for western food, but also for schools, institutions, families and Chinese restaurants. Over time, this soup has formed various schools and branches in Shanghai, among which the most representative ones are "restaurant school", "canteen school" and "home school". Among them, the "catering group" is represented by Huaihai Western Restaurant.
