A Chinese mooncake is a traditional pastry typically enjoyed during the Mid-Autumn Festival. It has a round shape symbolizing unity and togetherness. The mooncake is often filled with rich ingredients like lotus seed paste, red bean paste, or salted egg yolk, encased in a soft, thin pastry crust. Mooncakes are shared among family and friends as a symbol of reunion and are often intricately designed with decorative patterns on top.
