In Russia, there is a very classic traditional soup called "Luo Songtang", which is one of the traditional Russian cuisines. This is a thick vegetable soup that originated in Ukraine. It is mainly composed of beet, carrot, potato, spinach, cream, beef pieces, etc. This is a sweet soup with thick texture, purple color and strong smell, much like a thick stew. In different parts of Russia, Luo Songtang uses different materials, so the color of soup will be very different, including red, orange, green and so on. Most of them are used with bread.

This Russian Luo Songtang was introduced to Shanghai because of the October Revolution. Since then, this "western soup" has been gradually accepted by Shanghainese and improved. The most authentic Russian "Luo Songtang" tastes spicy, sweet and sour. It is unique and not suitable for the tastes of Shanghainese, so in the hands of Shanghainese, the spicy taste in Luo Songtang was removed and some tomatoes were added. The improved taste is sweet and sour, not so thick, and it will be smoother, and gradually become the "Luo Songtang" with unique Shanghai characteristics.

Three types are also derived. Luo Songtang in the restaurant will retain the traditional Russian flavor, with a strong flavor and beet as the main ingredient. Luo Songtang in the alley is packed in a big insulated teapot, which has the lightest taste. It has little to do with Russian Luo Songtang. It is more like a rice soup with clear soup and little water. The taste of Luo Songtang at home is most suitable for Shanghainese. If you thicken it with water starch, the soup will be smoother, more palatable and sweeter.

This Russian Luo Songtang is also called "Su Bo Tang" in Harbin, China. The ingredients used in cooking are different from those used in Shanghai. It is cooked with fresh cabbage, potatoes, tomatoes, fragrant leaves and beef, and the soup base is made of beef bones. The taste and taste will be very rich and delicious, and the taste of beef will be very strong. In winter, Harbin people will cook Supo soup at home.

As more and more people in China began to like Luo Songtang, Luo Songtang began to appear in many areas, but beef was mostly replaced by pork. The main vegetables are tomatoes and cabbage, stewed with potatoes. Luo Songtang made of pork is not as thick as beef, but sweeter and less oily. If you want to do Luo Songtang at home, it's also very convenient. There is a lazy Luo Songtang that is very suitable for cooking.
