Dried Ponmo is made from the Cow skin and expands up to three times original size when soaked in water for four hours or more. We all know that our soup may be incomplete without ponmo (cow skin). It doesn’t matter the soup you are making. You just need to soak the dried ponmo overnight and voila, your ponmo is ready to be cooked. Our dried ponmo is well preserved and doesn’t smell and it can last weeks in your kitchen counter or refrigerator without spoiling. 10-12pcs in a ring pack.
