How to make Du Xun shortbread?

"Du Xun crisp candy" originated from "peanut candy" about 2500 years ago. At that time, China was in the famous Warring States Period, and wars broke out again and again. So many surplus families boiled sugar and peanuts together before fleeing the war, and cut them into irregular small pieces to carry with them as dry food to supplement energy, which is the earliest "peanut candy".

1279, Zhao Ruohe, a descendant of the royal family (the tenth grandson and brother of Midea) took refuge in Zhangpu, Fujian Province, built Zhaojiabao in Zhangpu, changed his surname to Zhao Weihuang, and began to live in seclusion. Because of the long distance, the Zhao royal family needed high-energy dry food, so they inadvertently brought the traditional craft of making crisp candy in the court to Zhangpu, Fujian. This kind of palace crisp candy is made of selected crispy peanuts, white sugar, earth lard and onion, and has the characteristics of "crisp, crisp, fragrant and sweet" through ancient manual techniques such as one pick, two stir-frying, three boiling, four boiling, five coagulation and six cutting.

During the Kangxi period of Qing Dynasty, Cai Shiyuan, a native of Zhangpu, and his nephew Cai Xin became Emperor Qianlong and Emperor Jiaqing respectively. Cai Xin was ordered to go straight to the study to serve the prince and give lectures in imperial academy. He served in North Korea for 50 years, served as a minister in various ministries, such as official, ceremonial, military, criminal and industrial affairs, and served as a university student in Wenhua Hall and imperial academy affairs. Both uncles and nephews love to eat crisp candy from their hometown. They often ask people to bring crisp candy from Du Xun Town in Zhangpu to Beijing as special gifts for officials and friends. Emperor Qianlong's mouth was full of patterns, only to see crisp sugar golden, peanuts full, lard onion fragrant. A bite is crispy and delicious, and I am full of praise for Du Xun's crisp candy. Du Xun crisp candy was gradually sought after by officials and the royal family, and became popular in Beijing, becoming a good snack. Under the recommendation of Emperor Cai Xin, Emperor Jiaqing later ordered the imperial chef in the palace to imitate Du Xun's crisp candy, improved the technology, and achieved the same famous "Jing Crisp Candy".
