Turning air, time and memory into food opens up a special sense of ritual. In the memory of many Hong Kong people, eating Western food with soy sauce was once a rare event in a year. Western food with soy sauce is a localized Western food that combines Cantonese ingredients with Western cooking. It is named because soy sauce is often used for seasoning. Soy sauce in Cantonese is soy sauce, and soybeans are the main ingredient. Various auxiliary ingredients are added to make a Western sauce that is more suitable for Hong Kong tastes, which is full of ritual and Hong Kong's pragmatism.
