Cantonese Steamed Egg Custard (Zheng Shui Dan)
Zheng shui dan: silken steamed egg custard — the Cantonese answer to Japan's chawanmushi. Eggs beaten with warm chicken stock at a 1:2 ratio, strained until smooth, covered with film or a plate, and steamed over very gentle heat until set. The surface should be smooth as silk, not pocked or bubbled.

The Method
1
Beat the eggs thoroughly in a bowl. Warm the chicken stock to lukewarm — it must be neither cold nor hot, as either extreme will cause the custard to curdle. Pour the stock into the eggs in a steady stream, stirring gently, maintaining the 1:2 ratio of egg to stock. The mixture should be pale, even, and fully combined.
2
Strain the mixture twice through a fine-mesh sieve into your serving bowl or bowls, removing all chalazae and air bubbles. The surface of the strained liquid should lie perfectly still and unblemished.
3
Cover the bowl tightly with cling film or set a plate directly over it. This is where the dish lives or dies: the cover prevents condensation droplets from falling onto the surface and pocking it during steaming. Place in a steamer set over very gentle heat — ideally 60–70°C, never over vigorously boiling water. A folded towel laid over the steamer lid will absorb further condensation.
4
Steam over this low, steady heat until the custard is just set. Insert a toothpick at the centre — it should come out just barely clean. The surface, when the cover is lifted, must be smooth as silk, with no pocking, bubbling, or cratering.
5
Remove from the steamer. Finish by spooning oyster sauce and sesame oil over the surface, then scatter the sliced spring onion. Serve immediately in the vessel it was cooked in.
From the canon — Oyster sauce was invented by accident in the 1880s in Guangdong province when a cook named Lee Kum Sheung left oyster soup simmering too long and discovered … Oyster Sauce (Cantonese — Original Method vs Commercial) →

Quality Hierarchy
01
Reserve — Free-range eggs with deep-orange yolks; rich, home-made chicken stock reduced to a light gelatin; toasted sesame oil pressed from roasted sesame.
02
Estate — Good free-range eggs; a careful restaurant-quality chicken stock, well-seasoned and clear; decent cold-pressed sesame oil.
03
Market — Fresh supermarket eggs; a clean, low-sodium bought chicken stock; standard sesame oil.
04
House — Any fresh egg; diluted stock cube broth; any sesame oil to hand — the technique still produces a serviceable, silken result.

Sensory Tests
◇Touch. A toothpick inserted at the centre comes out just barely clean — the custard is set but retains the faintest quiver.
◇Sight. The surface is smooth as silk: no bubbles, no pocking, no craters, no weeping liquid around the edges.
◇Sound. The steam around the lid is a faint, low whisper — not the aggressive hiss of boiling water, which signals dangerously high heat.
◇Where it lives or dies. The custard is decided the moment it enters the steamer: heat too fierce or the surface left uncovered, and condensation and violent steam will pit and curdle it beyond rescue.

What to Pour
A light, dry Chinese rice wine (Shaoxing served warm) or an unoaked, neutral white — something that will not overwhelm the custard's silky, neutral-savoury delicacy. Fragrant green tea is the non-alcoholic companion of choice.
