Cantonese Cha Siu Bao (BBQ Pork Bun) — Baked and Steamed
Cha siu bao: the most iconic Cantonese dim sum — BBQ pork (char siu) filling encased in two versions: baked (baked bao with golden top that splits into a petal flower pattern); or steamed (fluffy white yeast-leavened bun). The baked version is a landmark of Hong Kong bakeries — the split top formed by scoring before baking. The steamed version is the 'Heavenly King' of dim sum.

The Method
1
Make the filling. Combine the char siu pieces with the oyster sauce and honey in a small pan over medium heat, stirring until the glaze coats the pork and thickens to a consistency that just clings — you want savoury-sweet, not candy-like, so pull the pan off the heat the moment the sauce falls slowly from the spoon rather than running freely. Spread the filling on a tray and cool completely before using, so that warm filling does not soften and tear the dough when you wrap it.
2
Make the baked bao dough. Sift the flour and baking powder together, then rub in the lard until the mixture resembles coarse crumbs, so the fat is distributed evenly and the finished bao will be tender rather than dense. Add the sugar, one beaten egg, and lukewarm water; bring together into a smooth, pliable dough, then rest it covered for 20 minutes so the flour fully absorbs the liquid and the dough becomes yielding and easy to stretch without springing back.
3
Divide the baked dough into 6 equal portions, flatten each into a round, place a portion of filling at the centre, and gather the edges upward, pinching firmly to seal, then place sealed-side down on a lined baking tray. Score three lines across the top of each bao with a sharp blade and brush once with beaten egg wash — the scoring is the structural decision that gives the top a path to bloom open into clean petals rather than crack at random, and this is where the baked bao lives or dies. The pinched seal faces down so that any gap is hidden and the top presents smooth for scoring.
4
Apply a second coat of egg wash over the scored tops so the surface builds up enough colour to turn a deep, even golden-brown without the dough drying out beneath. Bake in an oven preheated to 200 °C for 18–22 minutes; the bao is ready when the top has split open into a petal pattern and the split gapes cleanly — an uneven tear tells you the scoring was too shallow or the oven too cool.
5
Make the steamed bao dough. Dissolve the yeast and sugar in lukewarm water and allow to activate for 5 minutes, so you can see the mixture turn cloudy and faintly foamy before it meets the flour — dead yeast at this stage means flat bao later with no recovery. Add to the flour, bring together into a smooth dough, and knead for 8–10 minutes until the surface is entirely smooth, then cover and prove until doubled in size; punch down, knead in the baking powder so it is distributed evenly throughout the crumb, divide into 6 portions, shape each around a portion of filling with the base sealed tightly, set on small squares of parchment, and prove a second time until visibly puffed and light — a finger pressed gently into the side should spring back slowly, because a flat bao at this stage is an under-proved bao.
6
Place the proved steamed bao in a cold steamer, then bring it to maximum heat and steam on the highest possible heat for 12–15 minutes without lifting the lid, so the steam builds steadily and the bao rises in one controlled surge rather than collapsing from a sudden drop in temperature. The bao is done when it has expanded, the surface is smooth and matte, and the dough feels set — not tacky — when a fingertip grazes the side.
III
Quality Hierarchy
01
Reserve — Char siu sourced from a specialist Cantonese roast-meat house; lard rendered from fresh leaf fat; low-protein cake flour for the steamed dough to guarantee a white, cloud-like crumb.
02
Estate — Homemade char siu roasted to order; good-quality lard from a butcher; strong egg wash applied in two coats for maximum caramelisation on the baked bao.
03
Market — Char siu from a reputable Chinese barbecue counter; standard plain flour for both doughs; single egg wash on the baked version.
04
House — Shop-bought char siu; vegetable shortening in place of lard; all-purpose flour throughout — the character of the dish is present, the refinement is not.

Sensory Tests
◇Sight. The baked bao top has split into a clean petal-flower pattern and is a deep, even golden-brown across the whole surface.
◇Sight. The steamed bao has expanded to a smooth, matte dome with no wet or sunken patches on the surface.
◇Touch. A gentle fingertip press on the side of a proved steamed bao rebounds slowly — full proof achieved; no rebound indicates over-proving.
◇Touch. The crust of the baked bao yields with slight resistance but is not hard — the enriched dough has set through without drying.
◇Smell. The filling, while glazing in the pan, gives off a roasted, honey-tinged savouriness — the moment the raw oyster-sauce edge disappears marks readiness.
◇Where it lives or dies. The scored top of the baked bao must be cut before the oven: without those three incisions, the enriched dough has no path to bloom, and the bao bakes closed and dense rather than splitting into its signature petal pattern.
