In this video, you will see how mooncakes are made by a pastry chef from Maxim's, Hong Kong's biggest mooncake manufacturer.
And why do the Chinese have this tradition of having mooncakes during the Moon Festival?
During the Yuan dynasty (A.D.1280-1368) China was ruled by the Mongols. Leaders from the preceding Song dynasty (A.D.960-1280), unhappy at submitting to foreign rule, set out to coordinate a rebellion without being discovered. The leaders of the rebellion, knowing that the Moon Festival was drawing near, ordered the making of special cakes. Packed into each moon cake was a message with the outline of the attack. On the night of the Moon Festival, the rebels successfully attacked and overthrew the government. What followed was the establishment of the Ming dynasty (A.D. 1368-1644). Today, moon cakes are eaten to commemorate this legend.
