Some Important Points

The colour of the mooncake crust comes from alkaline water and golden syrup, and another function of the golden syrup is to keep the crust soft and also is the classic taste of Cantonese mooncakes. The delicious mooncake crust is soft and does not stick to your teeth. It will taste better with hot tea.

After several productions, we have observed that if want to make well mooncakes, the amount of golden syrup must be handled properly, too much will collapse and too little will dry up. Another possibility that the mooncake crust may burst is that the filling is not dry enough, the water content in the filling will evaporating during the baking process then causes the crust to crack. It is worth mentioning that the purple sweet potato filling must be steamed and blended to keep a beautiful purple colour, otherwise direct blend the raw purple sweet potato, it will become dark grey.

Information from The interneti

The origin of doll mooncake, there are two-story. One is that the bakers used leftover materials after making mooncakes to avoid wasting. So they made up and cooked them into pig cage mooncakes. Another way to say that is the baker must first test the influence of the oven temperature on the softness of the crust to determine the temperature before baking the mooncake. Of course, those “experimental products” are without filling. In the early days, there was no need to buy mooncake biscuits. When customers bought the mooncakes. The store would give out the mooncake biscuits as a gift together with the plastic cage. It was also explained that gift-giving emphasizes the need to “make a pair”. Therefore, buying mooncakes and giving pig cage mooncakes makes up the number.
