"Silk doll" is named after a small thin-skinned cake, which is wrapped with a lot of "silk". Also known as vegetarian spring rolls. First, make a thin crust cake with flour, about two inches in diameter. Then, the consumer personally put in a small amount of kelp, shredded radish, bean sprouts, pickles, broken ears, fried soybeans and so on. Then roll the bread into a tube and fill it with spices made of pepper and soy sauce. A "silk doll" is made and put into your mouth, which is crisp, cold and sour.
