Ground pork and napa filling is one of the most popular fillings in China. Here is how I make my own fillings! All you need are Napa， lean ground pork, fat ground pork, light soy sauce, dark soy sauce(both can be opurchased at Chinese grocery store), sesame oil, salt.The amount is flexable accorind to you taste. I used a media size napa, 900 gram lean ground pork, 400 gram fat ground pork. These can make many buns and dumplings that are enough for several days! My video is just a reference for you. They are tasty! Wish you can learn easily and will ike them too!
