Dough
Filling
200 g ground pork (about 70% lean, 30% fat) 1 scallion, finely chopped 10 g fresh ginger, grated Sauce Base
1 tbsp vegetable oil (15 ml) 1 tbsp soybean paste (黄豆酱, Chinese soybean paste) 1 tbsp sweet bean paste (甜面酱, sweet wheat bean paste) Instructions
Heat the oil in a small saucepan over medium-low heat. Add the soybean paste and sweet bean paste and stir-fry until fragrant. Add the water and stir well. Simmer until slightly thickened. Remove from heat and allow to cool completely. Seasoned Oil (Liaoyou / Aromatic Oil)
Ingredients
1 scallion, cut into sections ½ tsp Sichuan peppercorns Instructions
Place all ingredients in a small saucepan with cold oil. Heat gently over low heat. Cook until the scallion and ginger turn golden brown. Remove from heat and cool completely. You will need about 1–1½ tbsp (15–20 ml) of this aromatic oil for the filling.
Prepare the Filling
Mushrooms
Blanch the shiitake mushrooms in boiling water for 1 minute. Drain well and squeeze out excess moisture. Season the Pork
In a large bowl, combine:
All of the cooled sauce base 2 tsp light soy sauce (10 ml) 2 tsp oyster sauce (10 ml) Mix thoroughly.
Add Water
Gradually add:
Add in 2–3 batches, stirring vigorously in one direction until the meat absorbs all the liquid and becomes sticky.
Finish the Filling
Add:
1–1½ tbsp aromatic oil (15–20 ml) Mix thoroughly.
Cover and refrigerate for 30 minutes before use.
Make the Dough
Combine the flour, yeast, and sugar. Knead until a smooth dough forms. First Proof
Temperature: approximately 35°C (95°F) Allow the dough to double in size.
Shape the Buns
Divide into 5–6 portions. Roll each portion into a wrapper, thicker in the center and thinner around the edges. Fill with the pork mixture and seal. Steam
Place the buns into a steamer lined with parchment paper or lightly brushed with oil. Start with cold water in the steamer. Bring to a boil over high heat. Once the water is boiling, steam for 15 minutes. Turn off the heat and let the buns rest in the steamer for 3–5 minutes before opening the lid. Serve hot.
Notes
The aromatic oil is important and should not be replaced with sesame oil. It provides a deeper savory flavor without overpowering the filling. The combination of soybean paste and sweet bean paste gives the filling its characteristic rich "baozi shop" flavor. Blanching the mushrooms helps remove excess moisture and prevents the filling from becoming watery.
