Introduction of traditional grass seed cake in Zhixingzhai

Trough cake, also known as "egg cake", is a traditional Chinese cake popular in northern China. The reason why it is called "trough cake" is that it is formed by baking with a trough-shaped mold. According to Qing Chao, "Beijingers are afraid of the word' egg', and cakes are said to be at a low ebb, so is making cakes". The production history of trough cakes is very long, even dating back to the Ming and Qing Dynasties. It is said that both Emperor Qianlong and Empress Dowager Cixi love to eat cake, especially at breakfast. According to the documents of the Ministry of Internal Affairs of the Qing Dynasty, the cakes carefully made in the pastry room (later merged into the imperial dining room) in the palace at that time were not only for the palace to eat, but also as special offerings for ancestor worship.
