Sandingbao is a famous spot in Yangzhou, winning by flour fermentation and fine stuffing. Yuan Mei, a man of the Qing Dynasty, said in "Suiyuan Food List": "Yangzhou has the best fermented noodles and a high degree of relaxation." The flour used for fermentation is "white as snow", and the fermented dough is soft and tough and does not stick to teeth. Fuchun Tea House has always maintained the traditional characteristics of this fermentation. The stuffing of Yangzhou Sanding steamed stuffed bun is made of diced chicken, diced meat and diced bamboo shoots, hence the name "Sanding". Chickens are selected from hens every other year, which are both fat and tender; Diced pork ribs with moderate fat are selected, and diced chicken, diced pork and diced bamboo shoots are matched according to the ratio of 1: 2: 1. Diced chicken is big, diced meat is medium, diced bamboo shoots are small, and the particles are distinct. Diced chicken, also known as the three delicacies, is integrated with relish. I didn't feel hungry until noon in the morning. According to legend, the Japanese emperor ate Yangzhou Sanding steamed stuffed bun which was airlifted to Tokyo, and praised it as the best in the world.
