steamed cake/bun made of glutinous rice with sweet filling

Aiwowo, a traditional snack in Beijing, is served in snack bars in Beijing around the Lunar New Year every year and sold until late summer and early autumn, so Aiwowo is also a spring and autumn variety, and it is now available all year round. Love Wowo has a long history. Liu Ruoyu, an internal supervisor during the Wanli period of the Ming Dynasty, said in "Deliberation in Records": "It is also true that glutinous rice with sesame seeds is used as a cold cake and pills are used as a nest." It can be seen that this kind of food is washed and soaked with glutinous rice, then steamed in a steamer, cooled and kneaded evenly, pulled into small doses, pressed into round skins, wrapped with peach kernels, sesame seeds, melon seeds, green plums, golden cakes and sugar, and mixed into stuffing, which became the food called Wowo in the Wanli period of the Ming Dynasty. But why did it become a love nest later? I found the explanation in Li Guangting's book "Village Proverbs to Solve Yi" in Qing Dynasty. Because an emperor loved this kind of nest, when he wanted to eat it or wanted to eat it, he ordered, "Love the nest." Later, when this kind of food was introduced to the people, ordinary people could not and dared not say the word "imperial", so they omitted the word "imperial" and called it "love nest". This snack has flowed into the people in the Ming Dynasty, and it was recorded in the Ming Dynasty's "-"that there was aiwowo among the popular delicacies.
