Your new skill: Allow the resting time and work carefully through shaping or assembly.
These soft buns use a sweet cooked-egg-yolk filling rather than liquid custard. Chill the filling while you make the dough so it is easier to enclose.
Your ingredients
Get ready: Bowls, spoon, rolling pin, baking-paper squares and covered steamer.
- Filling: 3 yolks of hard-boiled eggs, or cooked salted duck egg yolks
- Filling: 50 g unsalted butter, softened
- Filling: 30 g sugar
- Filling: 30 g full-fat milk powder
- Dough: 175 g bao flour/cake flour, or plain flour
- Dough: 1 tsp instant dry yeast
- Dough: 1 tsp baking powder
- Dough: 1 tbsp sugar
- Dough: 1 tbsp neutral cooking oil
- Dough: 90 ml lukewarm water
Let’s make it
-
Make the filling
Mash the cooked yolks finely while warm. Mix with softened butter, sugar and milk powder until smooth, then refrigerate to firm slightly.
-
Mix and knead
Mix dough flour, yeast, baking powder, sugar and oil. Gradually add lukewarm water to make a soft, non-sticky dough. Cover for 10 minutes, then knead until very smooth.
-
Wrap eight buns
Divide dough into eight and keep covered. Roll each into a disc about 9 cm across, with thinner edges. Divide filling between them, bring edges together and seal completely.
-
Let them puff
Put buns seam-side down on paper squares in the steamer, leaving room between them. Rest for about 30 minutes until light and plump, not necessarily doubled.
-
Steam and serve
Set over boiling water, cover and steam for about 8 minutes, longer if needed until dough is cooked through. Lift the lid away from your face. Let the hot filling cool a little before biting.

Keeping it: Cool promptly, put in a covered fridge container within 1–2 hours and use within 48 hours. Reheat only once until steaming hot throughout. Freeze spare cooked portions promptly if you need longer, thaw in the fridge and reheat until hot through.
