Mooncakes

Mooncakes (yue bing) are the defining food of the Mid-Autumn Festival (Zhong Qiu Jie), celebrated on the fifteenth day of the eighth lunar month — typically in September or early October — when the moon is at its fullest and brightest of the year. The festival is a family occasion focused on moon-gazing, lanterns, and the exchange of mooncakes between households, which has generated one of the most lucrative gifting economies in Chinese retail: mooncake gift boxes, launched by hotels, bakeries, and companies from late August, are a significant commercial and social obligation across China.

The canonical form is the Cantonese-style mooncake: a thin, firm pastry shell — made from a dough of flour, golden syrup, and alkali solution that produces the characteristic shiny, yielding skin — pressed in a mould that imprints elaborate decorative patterns and Chinese characters on the surface. The filling is dense and smooth, typically lotus-seed paste (lian rong) sweetened with sugar, or red bean paste, or a mixed-nut filling. Embedded in the centre of the filling are one or two whole salted duck egg yolks, which represent the full moon. The yolk's salt and richness contrasts with the sweet filling.

Suzhou-style mooncakes (su shi yue bing) use a multi-layered puff-pastry shell rather than the Cantonese skin — flakier, lighter, and less sweet overall, with sweet or sometimes lightly savoury fillings including minced pork. The pastry shatters into crumbs when cut; the two styles are quite different eating experiences.

Snowy mooncakes (bing pi yue bing) are a modern Cantonese invention: a chilled or frozen outer layer made from glutinous rice flour gives a soft, mochi-like wrapper in white or coloured varieties, enclosing fillings such as mango custard, red bean ice cream, or chocolate ganache. These require refrigeration and have a much shorter shelf life than baked mooncakes.

A full Cantonese mooncake is dense and rich; portions are small. The standard serving is one mooncake cut into four or six wedges and shared between the whole table.
