Flower cake was created by a baker in the Qing Dynasty more than 300 years ago. It is widely spread because of its floral fragrance, sweet but not greasy, and beauty. The "Yanjing Sui Lu" in the late Qing Dynasty recorded: "April flowers made of roses are called rose cakes. Those made of wisteria flowers are called wisteria cakes. They are all seasonal foods." Edible roses The flowering period of flowers is limited, and this kind of cake uses only edible rose petals, which is one reason why the flower cake is quite precious. With the rising reputation of flower cakes, the tributes made by officials in the court made one of them become the imperial palace, and won the favor of Emperor Qianlong, and won his appointment: "In the future, the rose cakes used for worshipping gods don't need to be invited again. Can."
