What You’ll Need (Ingredient Highlights)
Plain (all-purpose) flour – Forms the base of the soft bao dough.

Baking powder & yeast – Creates the signature fluffy texture.
Char siu pork – Use leftover or homemade BBQ pork for authentic flavor.

Pro Tips Before You Start
Warm water activates the yeast faster. Avoid hot water.
Chill the filling so it’s easier to wrap and won’t make the dough soggy.
Flour your surface well when rolling and shaping.
Use parchment paper under buns to prevent sticking while steaming.
Don’t overcrowd your steamer—give buns space to expand.
How to Make Char Siu Steamed Buns
Step 1: Make the Dough
In a large bowl, mix flour, milk powder, baking powder, yeast, and sugar.
Make a well, pour in warm water and oil, and mix until a dough forms.
Knead for 10 minutes until smooth.
Cover and let rest in a greased bowl for 1 hour or until doubled in size.
Step 2: Cook the Filling
Heat oil in a skillet over medium-high heat.
Add onion, garlic, and a pinch of salt.
Cook until softened. Stir in diced char siu pork, char siu sauce, soy sauce, sugar, and water.
Simmer 3–4 minutes, then stir in the cornflour slurry.
Cook until thick. Spread on a tray and place in the freezer to cool for 15 minutes.
Step 3: Roll and Shape Dough
Roll dough into a rectangle, then fold and roll again 2 more times.
Roll into a log and cut into 16 equal pieces.
Flatten each piece, then roll edges thinner than the center to make a disc.
Step 4: Fill and Shape Buns
Place 2 heaping tablespoons of cooled filling in the center of each disc.
Pleat and pinch edges to seal the bun.
Place seam-side down on parchment-lined tray.
Cover with damp towel and rest 1 hour.
Step 5: Steam the Buns
Place buns in a steamer over boiling water.
Cover and steam for 10 minutes until fluffy and cooked through. Serve hot.
