Shanxi famous food-Liulin sesame seed cake originated in Pumiao, Nalou, Liuwei, Zhonghe and other towns and villages. It was originally a holiday snack for Yongning people in the New Year. Now only a few elderly people can cook this snack, which is almost lost. The crust made of rice flour, the cake core made of yellow sugar and several kinds of millet are baked in a red-hot iron pot and sprinkled with sesame seeds. Its ugly round cake, crisp cake surface chewed in the mouth, sweet cake core and sesame fragrance seeped out and slowly spread in the mouth.
