Step 1

Add oil to a pan. Fry onion until slightly golden.

Step 2

Pour in water. Then add oyster sauce, Char Siu sauce and dark soy sauce. Leave it to boil for 30 seconds. Use a slotted spoon to remove the onion.

Step 3

Turn the heat to the lowest. Mix the starch water very well then pour in. Stir constantly until the liquid turns into jelly. Transfer to a bowl to cool.

Step 4

Coarsely chop Char Siu into small pieces. Add to the jelly. Mix well and set aside.

Step 5

IF USING HANDS: Mix flour, sugar, baking powder, yeast and oil in a bowl. Add water gradually while mixing with a pair of chopsticks/spatula. Combine with your hands to form a dough. Rest (covered ) for 10 mins then knead again until very smooth.

Step 6

IF USING A STAND MIXER: Add all the ingredients for the dough into the mixing bowl. Knead on low speed for about 8 mins until a smooth dough forms.

Step 7

Divide the dough into 14 equal parts. Work on one piece at a time and make sure you cover the rest to prevent it from drying out.

Step 8

With a rolling pin, flatten one piece into a disc-like wrapper, 9-10cm in diameter. Ideally, it should be thinner on the edge & thicker in the middle (See the rolling technique in the video below).

Step 9

Place a spoonful of filling (about 20g) in the middle of the wrapper. To ensure a “crack open” effect after steaming, follow the folding technique shown in the video below to seal the bao. Alternatively, pleat the bao using the regular method introduced in my recipe for “Steamed Bao Buns, A Complete Guide”.

Step 10

Repeat to finish all the wrappers and filling. Then place the bao into steamer baskets lined with parchment paper to prevent sticking (Alternatively, brush a thin layer of oil if using a metal/plastic steamer).

Step 11

Leave to rest for 30 minutes or so until they become very light & plump (no need to cover).

Step 12

Bring water to a full boil in a wok/pot. Place the steamer baskets in. Steam over medium-high heat for 10 mins. Serve immediately.

Step 13

You can make extra filling for later use and store it in the freezer for up to three months.

Step 14

It’s not recommended to store uncooked bao. Instead, cooked bao freeze very well. Consume within three months.

Step 15

To reheat: Defrost in the fridge then steam for 3 mins. Alternatively, steam for 6 mins without defrosting.
