Custard and Salted Egg Yolk Snowskin Mooncake

Mid-autumn festival is just about two weeks away, and it is celebrated on the 15th day of the 8th month of the Lunar calendar. Mooncake, a round shape Chinese pastry, is traditionally eaten during the festival with family members to symbolize completeness and reunion. There are several types of mooncakes, but are mainly classified into baked and no-bake mooncakes. This year, I attempted to make my own mooncakes, known as snowskin mooncake (冰皮月饼), which does not require baking and must be kept chilled.

To make snowskin mooncake, cooked glutinous rice flour is required. I bought it directly from a baking supply store, or you can also cook it yourself using raw glutinous rice flour. To do so, simply cook the glutinous rice flour without any oil in a frying pan over low to medium heat, stirring occasionally. Once the glutinous rice flour turns slightly yellowish or ivory, it is cooked. Let the cooked flour cool down completely before using.

Kou Fien” or cooked glutinous rice flour is a main ingredient for the snowskin. We also need mooncake moulds, which are traditionally made of wood but nowadays plastic moulds are quite common as well.
