After that, Aunt Xue began to boil the milk, which might be cow's milk.
She added frosting and glutinous rice flour to the milk, stirred them with a stirring rod until the sugar was completely dissolved.
She then let it simmer over low heat, stirring constantly.
At first, it was watery and not thick at all, but as the temperature rose, the milk would gradually thicken.
When it finally turned into a very thick paste, she took the milk pot off the fire.
Because the temperature inside the pot was still quite high, she had to keep stirring for a while to keep the paste smooth and lump-free.
Then, while it was still hot, she used a spatula to pour the milk paste into a greased wooden tray, smoothing the surface as much as possible, before leaving it outside to cool.
Meanwhile, Aunt Xue prepared another bowl of glutinous rice flour, a bowl of beaten eggs, and some toasted breadcrumbs.
