In the sixth year of Xichun (A.D. 1 179), the sun was shining in March of spring. Song Xiaozong was lucky enough to call a businessman by the lake outside Xizi Qiantang to ask about his native place, life experience and business. Song Wusao was among them. When asked about Song Wusao, she said, "I come from Tokyo and have been here with my late emperor for fifty years." Xiaozong was deeply moved when he saw the old woman with silver hair, so he moved to Song Wusao's shop to have a rest. Song Wusao was so happy that she immediately rolled up her sleeves and went to the kitchen to make a plate of vinegar fish for Xiaozong to taste.
Xiaozong is used to eating delicacies on weekdays, but I didn't expect the crispy fish skin in vinegar to be tender and delicious, and the taste is much better than that of imperial food. He praised: "It's delicious!" Now give Song Wusao one hundred colorful satin horses. Thanks to Lord Wancheng's reward, the vinegar fish of Sister-in-law Song is famous all over the world. It was copied everywhere and passed down from generation to generation as a famous dish. Hangzhou's Louwailou, Wuliuju, because of the vinegar fish business, business has been booming for hundreds of years.
Song Wusao was a folk woman in the early Southern Song Dynasty. She was originally from Tokyo, the capital of the Northern Song Dynasty (now Kaifeng, Henan). She is good at cooking, especially at cooking fish. In the first year of Jingkang (A.D. 1 126), the nomads invaded the south on a large scale, the capital fell, the Qin and Hui emperors were exiled to the north, and the Northern Song Dynasty was declared extinct. The following year, Kang Wang established the Southern Song regime in Jiangnan, with its capital in Lin 'an. Song Wusao went south with the tide of refugees and lived outside Qiantang Gate of West Lake in Lin 'an. In order to make a living, she returned to her old job. Luo Zhang opened a small hotel to receive tourists from east, west, north and south.
Lin 'an is located in the southeast coast, and there are many kinds of fresh fish in the offshore and West Lake. Men, women and children like to eat fish, and restaurants and restaurants inside and outside the city cook countless dishes with fish. Song Sao is determined to innovate. After a period of deliberation and experiment, she used vinegar as the main seasoning, supplemented by ginger, garlic, sugar and salt, and cooked a novel fish dish with good color, fragrance and taste, named "vinegar fish". Once the vinegar fish of Wusao Song came out, it immediately attracted many diners, all kinds of people came here, and the business in the store became prosperous.
