Yam Cake is a popular Chinese snack that is made from grated yam and rice flour. It has a soft and slightly sticky texture with a savory and fragrant taste. The yam is mixed with a combination of dried shrimp, mushrooms, and Chinese sausage, which adds a rich umami flavor to the cake. It is then steamed until cooked through and topped with a crispy fried shallot garnish. Serve it as an appetizer or as part of a dim sum spread.
