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. Stir until the glaze coats the pork and thickens to a consistency that just clings — the filling should read as savoury-sweet, not candy-like. Spread on a tray and cool completely before using.

Make the baked bao dough. Sift the flour and baking powder together. Rub in the lard until the mixture resembles coarse crumbs. Add the sugar, one beaten egg, and lukewarm water; bring together into a smooth, pliable dough. Rest, covered, for 20 minutes. The dough should feel soft and yielding, not sticky.
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. Place sealed-side down on a lined baking tray. Score three lines across the top of each bao with a sharp blade. Brush once with beaten egg wash. The scoring is the structural decision that allows the top to bloom open during baking — this is where the baked bao lives or dies.
4
Apply a second coat of egg wash over the scored tops. 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 is a deep, even golden-brown — the split should gape cleanly, not tear unevenly.
5
Make the steamed bao dough. Dissolve the yeast and sugar in lukewarm water and allow to activate for 5 minutes. Add to the flour and bring together into a smooth dough. Knead for 8–10 minutes until the surface is entirely smooth. Cover and prove until doubled in size. Punch down, knead in the baking powder, then divide into 6 portions. Shape each around a portion of filling, sealing the base tightly, and set on small squares of parchment paper. Prove a second time until visibly puffed and light — a finger pressed gently into the side should spring back slowly. A flat bao at this stage is an under-proved bao.
6
Place the proved steamed bao in a cold steamer. Bring to maximum heat and steam on the highest possible heat for 12–15 minutes without lifting the lid. 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.

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.
