It is said that 100 years ago, there was a family in Wuzhen, and the couple opened a small cake shop called Tianshun. They worked hard to find out the special formula and baking process, and the cake had a unique flavor and prosperous business. They have a son and a daughter. When the son got married, he decided not to pass on his daughter-in-law, which made his daughter very unhappy. One day, when she saw her sister-in-law just outside the window, she took the opportunity to sprinkle a handful of salt in the powder with the intention of destroying it. Unexpectedly, this kind of salty shortbread is very popular. The customer said that the previous shortbread was fragrant and sweet, and this time it was sweet and salty. The taste of salt and pepper was delicious! Later, my father learned that my daughter had added salt to the ingredients, and the name of "Crispy Sugar" spread like wildfire.
