Production: Spread the duck skin and spread mashed potatoes on the duck skin. Roll it up, seal the mouth with a toothpick, put it in a frying pan and fry it on low heat until the duck skin is oily. Take it out, add water to the steamer, and roll the duck skin into the steamer for about 20 minutes. Take out, cool, slice and plate.
Features: Because the duck skin has been fried, there is no feeling of greasy entrance.
