Most mooncakes consist of a thin tender skin enveloping a sweet, dense filling. The mooncake may contain one or more whole salted egg yolks in its center to symbolize the full moon. Very rarely, mooncakes are also served steamed or fried.

Traditional mooncakes have an imprint on top consisting of the Chinese characters for “longevity” or “harmony” as well as the name of the bakery and the filling in the moon cake. Imprints of the moon, the Chang’e woman on the moon, flowers, vines, or a rabbit (symbol of the moon) may surround the characters for additional decoration.

Mooncakes are considered a delicacy; production is labor-intensive and few people make them at home. Most mooncakes are bought at Asian markets and bakeries. The price of mooncakes usually ranges from $10 to $50 (in US dollars) or around £5 to £35 in pounds for a box of four although cheaper and more expensive mooncakes can also be found.
