Flip sugar, made from various materials, is the main decorative material used in making Font Cakes. It originated from the art of British cakes and is a popular cake decoration among Americans. The process dates back to the 18th century, when people began adding wild fruits to the cake and applying a layer of protein sugar (Royaling) to the surface of the cake To enhance the flavor of the cake. In the 1920s, three-layer wedding cakes became the mainstream. The bottom layer is used to entertain wedding guests for consumption, the middle layer is used to send guests home, and the top layer is reserved for consumption after the child's baptism ceremony
