Sam sun bean skin is a traditional snack in my hometown. The shops selling this traditional snack are mostly in the streets of Xianning, and the sellers have all practiced their unique skills. Most of the masters' practices are to mix mung beans and rice into pulp, spread it into thin skin in a pot, and pack stuffing inside. However, there are also exquisite masters who will pour a layer of brine juice on the bean skin. Brine juice is made of beef broth, and the rich taste makes the bean skin more delicious.
