Where did the red bean glutinous rice cake come from?

Red bean glutinous rice cake is a dish in Yanghe Town, Jiangsu Province. Red bean glutinous rice cake originated in Yanghe and has a long reputation. There is an interesting legend about its history: during the reign of Qing Qianlong, there was a small hotel in Yanghe ancient town. The owner's name is Zhang, and everyone calls him "Master Joe". The wife's name is "Aunt Joe" and the daughter's name is "Girl Joe". Master Qiao's family is skilled and prosperous. The local folks gave him a signboard of "Three Bridges Hotel" and a pair of couplets. The first part is: good at making Huaibei cakes; The bottom line is: skillfully cook Jiangnan cuisine. One year, Emperor Qianlong went down to the south of the Yangtze River and passed through Taoyuan (now Siyang) county. It is said that Yanghe ancient town has beautiful scenery and delicious food. So he and Ji Xiaolan overseas Chinese, a college student, disguised as businessmen, came to Yanghe by carriage. When I got to the street, I saw the couplets on the door of Sanqiao Hotel at a glance. Emperor Qianlong was quite unhappy: Hum! How capable the country shop is, how dare you boast about this Haikou? Even if I were a chef, I wouldn't dare to be so boastful. Too arrogant! Emperor Qianlong said, "Look at your small hotel, the couplets posted at the door are not small!" " Master Joe was all smiles: "Hee hee, the couplets at the door are from the villagers, so don't mind!" " "Emperor Qianlong sneered." Hey hey! I don't eat today. I make a cake according to the shape of my wheel. It's golden, crisp and sweet. It's delicious ... Ji Xiaolan took it: "I heard from the store that your name is Sanqiao." You have to be skillful and elaborate. If you can make this cake well, my master will be rewarded! "Emperor Qianlong went on to say," If you can't make this cake well, I will smash your signboard and tear your couplets! "The division of labor in the store immediately: Aunt Qiao is responsible for stuffing, Master Qiao is responsible for kneading dough, and Miss Qiao is responsible for rolling dough. In a short time, a delicious and delicious wheel cake was born in Yanghe town. With a straight face, Emperor Qianlong picked up chopsticks and looked around with wheel cakes. It is really golden, round and has gorgeous patterns. Very beautiful, can't find any flaws. He gently took a bite, only felt sweet and crisp, full of fragrance, very delicious, and could not find the slightest flaw; He chewed carefully and listened to the creaking sound. His voice is crisp and very pleasant, and he can't find any loopholes. Only then did Emperor Qianlong turn his anger into joy and sincerely admired Sanqiao Hotel for its "skillful hands and well-deserved reputation".
