Some of the ingredients in the filling are new to your guys so I will take some time to talk about it.
Sha Ge (沙葛) - It is also known as Jicama, or Mexican turnip. It tastes almost like a pear or water chestnut - sweet, crunchy, and juicy. If you can’t find it, you can use carrots, water chestnuts, or daikon radish as a replacement. We only need 1/2 of a cup, you can snack on the rest.
Cai Pu (菜脯) - It is Chao Zhou style preserved daikon radish. You want to get the Xian Cai Pu which is preserved with salt. There is another sweet kind that is preserved with sugar and salt. Don’t get the sweet one. If you can not get this ingredient, you can use pickled vegetables or Zha Cai (preserved Mustard stem)as a replacement.
Dou fu Gan (豆腐干) - compressed tofu (soybean curd). The texture is firm. The one that I get is braised in a spice brine, so it is salty and flavorful. There are other kinds of Dou Fu Gan that don’t that much flavor so you might need to adjust the seasonings base on what you use. You can look up the tofu section in your local Asian grocery, you should be able to find it. We need 1/3 cup of this.
Xia Pi (虾皮), translates as shrimp skin. It is sun-dried baby shrimps. They don’t have that much meat so they look like shrimp shelves. That’s why we name it Xiapi. We need 3 tbsp of this.
Soak 4 pieces of dried shitake mushroom with room temperature water 2 hours in advance. One they are re-hydrated, squeeze the water. Save the soaking liquid. Sliced the mushroom and diced it.
Marinade 10 ounces of ground pork with the following ingredients: 2 tsp of soy sauce, 2 tsp of fish sauce, 1 tbsp of Chinese cooking wine, 1 tbsp of oyster sauce, 1 tbsp of satay sauce(optional) 1 tsp of sugar and some white pepper to taste. Mix until the flavor is well combined. Set it aside.
Besides that, you will also need to dice 1 shallot, 2 cloves of garlic, and 1.5 tsp of ginger. Set these aromatics aside.
Heat your wok. Add 2 tbsp of cooking oil along with all the aromatics. Stir for a few seconds. Then add the diced shitake mushroom, preserved radish, braised tofu, and the sun-dried baby shrimps. Keep stirring over medium heat for a couple of minutes. Toss in the diced jicama. The reason I add it a little late is that I want to keep the crunchy texture. Stir for another minute then push everything to the side. So we have room for the ground pork. The pork is seasoned. The shrimp, tofu, preserved radish already have flavors so you don’t need to add any more seasonings. Just stir to cook the pork through. It will take a few minutes. Turn the heat to low. Pour in some cornstarch water in batches (1/2 cup of the mushroom soaking liquid + 2 tbsp of cornstarch). This will help to bind the filling together. Give it a taste to make sure the flavor is good. Take it out. Set it aside and let it cool completely.
While waiting, dice 1/2 of a stalk of celery, and 1.5 cups of garlic chives. If you don’t like the flavor of the garlic chives, you can use spinach, scallion, or fennel. Combine the celery and the garlic chives. Add a big drizzle of toasted sesame oil. Mix well. We gonna mix the chives, celery with the filling together. The oil will help to wrap the chives and prevent it from releasing moisture after it touches the seasoning. Also, you want to mix the vegetables in when the pork is completely cool down so the chives don’t get soggy.
By the way, the local Chiuchow Fen Guo has roasted peanuts in the filling but I personally don’t like peanuts in the dumplings so I didn’t add it. Set the filling aside.
