Vinaigrette Broad Bean : a classic flavor originating from Chengdu, Sichuan Province. It is a popular snack of the same brand as that of Sichuan Airlines. We select high-altitude soybeans from Yunnan Province, which are plump in size. It is carefully soaked in Sichuan-style old vinegar for 48 hours, then coated with a thin layer of red sugar. When eaten, it combines a sweet and sour taste, with a crispy and not greasy texture. Whether it is used as a side dish with tea and wine, for reading and watching TV series, or for a small gathering with friends, a jar of old vinegar soybean can always brighten up your leisure time.
