In La Traviata written by the French writer Dumas, a dessert that won the heart of La Traviata Margaret was called Malden candy, but whenever a guest came to the door, he would send a big bag of Malden candy to please her. This is a French candy snack, which is actually a sugar-stained chestnut boiled in syrup. Some people say that it originated in Lyon in the south of France, while others say that it came from Italy in the16th century. Although it is only a small spot, it is extremely time-consuming and laborious to make. Chestnuts are shelled first, then carefully pried open the fluff skin on them, cooked, put into low-concentration vanilla syrup, boiled with slow fire, soaked for one day, then fished out to increase the concentration of syrup, then put chestnuts into boiling and soaking, and so on for several times, the concentration of syrup gradually increased, and finally added with sweet wine until the syrup was completely absorbed by chestnuts.
