Homemade bean skin
To get enough fat bean skin, first burn a pot of thick soy milk. When it is burned to the surface of the smoke and does not bubble, you can enter the fishing posture of Jiang Taigong, and scoop up the bean skin that grows every six minutes one by one and put it on the chopsticks. The Japanese have given such a rare food a subtle but apt name: "yuba" – a leaf that floats on top of the soup. Sashimi with wasabi and soy sauce is a Kyoto specialty.
