Ingredients

Dough

• 300 g all-purpose flour (medium gluten)
• 56 g sugar
• 1 tablespoon cooking oil
• 1 1/2 teaspoons baking powder
• 150 g water
• 11 g active dry yeast

Filling

• 300 g ground pork
• 300 g Chinese cabbage (Bok Choy can be substituted)
• 4 tablespoons water
• 1 tablespoon sesame oil (dark sesame oil recommended)
• 2 tablespoons soy sauce
• 1 teaspoon salt
• 1 teaspoon sugar
• 1 teaspoon rice wine
• 1 pinch pepper
• Minced green onion (optional)
• Minced gingerroot (optional)
• Minced garlic (optional)

Equipment Needed

• Large mixing bowl
• Measuring cups and spoons
• Steamer
• Parchment paper or cabbage leaves
• Rolling pin

Instructions

1. Activate the Yeast: In a small bowl, dissolve the active dry yeast in the water. It is important that the water is warm enough to activate the yeast, check your yeast packaging for instructions.
2. Combine Dough Ingredients: In a large mixing bowl, combine the flour, sugar, cooking oil, and baking powder.
3. Mix the Dough: Add the yeast mixture to the dry ingredients and mix until a smooth dough forms.
4. First Rise: Cover the bowl and let the dough rise for 40 minutes in a warm place.
5. Knead and Divide: After the first rise, knead the dough until smooth. Divide the dough into 30 equally sized portions.
6. Prepare the Cabbage: Briefly blanch the leaves of the Chinese cabbage (or Bok Choy) in boiling water.
7. Cool and Mince: Remove the blanched cabbage from the boiling water and immediately cool it in cold water. Mince the cabbage finely.
8. Strain the Cabbage: Strain the minced cabbage and squeeze out as much water as possible. The drier the cabbage, the better the filling will be.
9. Combine the Filling Ingredients: In a large bowl, combine the ground pork, strained cabbage, water, sesame oil, soy sauce, salt, sugar, rice wine, and pepper. Add minced green onion, gingerroot, and garlic (if using). Mix all ingredients until well combined.
10. Roll Out the Dough: Roll out each portion of dough into a small circle, roughly the size of your palm.
11. Fill the Buns: Place approximately one tablespoon of filling in the center of each dough circle.
12. Shape the Buns: This is the tricky part! Pinch the edges of the dough together tightly on top, overlapping to completely close the bun. Aim for a pleasing, symmetrical shape.
13. Second Rise: Arrange the filled buns on a baking sheet. Cover them and allow them to rise a second time for 40 minutes.
14. Prepare the Steamer: Bring water to a boil in a steamer.
15. Line the Steamer: Place pieces of parchment paper under each bun to prevent sticking, or line the steamer with cabbage or other leafy vegetables. This allows steam to circulate while preventing the buns from sticking.
16. Steam the Buns: Arrange the buns in the steamer, ensuring they are not overcrowded. Steam for 6-8 minutes over high heat.

Expert Tips & Tricks

• Dough Hydration: If the dough feels too dry, add water one teaspoon at a time until it reaches a smooth, pliable consistency. Conversely, if the dough is too sticky, add flour one teaspoon at a time.
• Even Cooking: Ensure the steamer lid is tightly sealed to maintain consistent steam and even cooking.
• Filling Flavor Boost: For a richer filling, consider adding a small amount of ground dried shiitake mushrooms. Rehydrate them in warm water before mincing and adding to the filling mixture.
• Shiny Buns: For a glossy finish, brush the steamed buns with a light coating of oil immediately after removing them from the steamer.

Serving & Storage Suggestions

Serve the Bao-Zi hot, straight from the steamer. They are delicious on their own or with a side of soy sauce or chili oil for dipping.

Storage:

• Room Temperature: Steamed buns will keep at room temperature for a few hours. However, they are best consumed fresh.
• Refrigerator: Store leftover buns in an airtight container in the refrigerator for up to 2 days. Re-steam or microwave to reheat.
• Freezer: For longer storage, freeze the buns individually on a baking sheet until solid. Then, transfer them to a tightly sealed freezer bag. They can be stored in the freezer for up to 2 months. Re-steam directly from frozen until heated through.

Reheating:

• Steaming: The best way to reheat steamed buns is by steaming them again for about 5-6 minutes, or until soft.
• Microwaving: Microwave them, covered with a damp paper towel, to prevent them from becoming rubbery. Sprinkle a little water on the bun before microwaving.

FAQs (Frequently Asked Questions)

Q: Why is my dough not rising?
A: The most common reason is that the yeast is not active. Ensure the water you use to dissolve the yeast is warm (not hot) and that the yeast is not expired. A cold room can also hinder the rising process; find a warm spot.

Q: How do I prevent the buns from sticking to the steamer?
A: Using parchment paper squares under each bun is a reliable method. Alternatively, lining the steamer basket with cabbage leaves or other leafy greens creates a natural, non-stick surface.

Q: My buns are coming out soggy. What am I doing wrong?
A: Make sure you are squeezing out as much water as possible from the blanched cabbage. Excess moisture in the filling can lead to soggy buns. Also, avoid overcrowding the steamer, which can trap moisture.

Q: Can I make the dough ahead of time?
A: Yes, you can prepare the dough ahead of time. After the first rise, punch down the dough, wrap it tightly in plastic wrap, and store it in the refrigerator for up to 24 hours. Allow the dough to come to room temperature before continuing with the recipe.

Q: How do I get the perfect pleated bun shape?
A: Practice makes perfect! Start by pinching the dough together at one point, then continue pinching and pleating the edges of the dough, overlapping slightly as you go, until you reach the starting point. Ensure the seal is tight to prevent the filling from leaking out.
