Mooncakes are a Chinese pastry typically eaten during the Mid-Autumn Festival, also known as the Moon Festival or Mooncake Festival, one of China's most important holidays. Amidst the celebrations, mooncakes are shared between family and friends. Often intricately decorated, mooncakes consist of a thin crust and a dense filling, usually of lotus seed paste or red bean paste. They may contain other special ingredients, such as yolks from salted duck eggs or nuts.
