Mooncakes are traditional Chinese pastries typically enjoyed during the Mid-Autumn Festival. They are round or square in shape and have a thick filling, often made from ingredients like lotus seed paste, red bean paste, or mixed nuts. Some mooncakes also contain salted egg yolks, symbolizing the full moon. These pastries are usually beautifully decorated and can be made with various crusts, including baked or snowskin. Families and friends often exchange mooncakes as a gesture of goodwill and to celebrate the harvest season, making them an important part of Chinese culture and festivities.
