Mooncake is a Chinese confection that is traditionally eaten during the Mid-Autumn Festival, although they can be eaten at other times of the year as well. Typical mooncakes are either round or rectangular puck-shaped pastries, measuring about 10 cm in diameter and 4-5 cm thick. They have a relatively thin crust (2-3 mm), which surrounds a thick pasty filling and may contain yolks from salted duck eggs. Mooncakes are typically rich, heavy, and dense compared with most Western cakes and pastries. It is usually eaten in small wedges accompanied by Chinese tea.
