Silky steamed egg custard (蒸水蛋)
zheng shui dan (蒸水蛋)
The gentlest confinement dish: eggs whisked with warm broth and steamed to a soft, savoury custard. Easy to digest and kind to a delicate first week appetite.
Most confinement dishes are built for the later weeks, rich with sesame oil, ginger and wine. Steamed egg is the exception: soft, warm and barely seasoned, it is one of the few substantial things the tradition is happy to serve in the first difficult days.
Why this dish
The early week is arranged around gentleness. Appetite is small, digestion is delicate, and the heavy warming dishes would be too much. A warm, silky custard of egg and broth gives real nourishment, protein the tradition considers tonifying, without asking anything of a tired system. It is comfort food in the most literal sense.
Getting the silk
There is only one technique to learn, and it is two numbers. Use about one and a half times as much warm liquid as beaten egg, and steam it low and slow. Sieve out the bubbles, cover the bowl so drips do not pit the surface, and stop while it still has a slight wobble. Get those right and it sets like glass every time.

Why this ingredient
Egg (鸡蛋)
Eggs are one of the quiet staples of the confinement kitchen, valued as a gentle, nourishing source of protein that the tradition considers tonifying and easy on a recovering system. Where the richer dishes are held back for the later weeks, steamed egg is one of the few substantial foods considered suitable from the very first days, which is why it appears so often in the early menu.
Ingredients
- 3 eggs, at room temperature Cold eggs steam unevenly; letting them warm up first gives a smoother custard.
- 270 ml warm chicken stock or water (about 1.5 times the volume of egg) The ratio is what makes it set silky rather than rubbery. Warm, not hot, so it does not start cooking the egg.
- 1/4 teaspoon salt Whisked into the liquid so it seasons evenly.
- 1 teaspoon goji berries, softened in warm water Optional, scattered on top for colour and a touch of sweetness.
- A few drops of sesame oil and a little light soy, to finish Added after steaming, not before, so the surface stays glossy.
Method
- 1 Whisk the eggs gently with the salt, trying not to whip in too much air.
- 2 Stir in the warm stock or water, then pour the mixture through a fine sieve into a shallow heatproof bowl. Sieving is what removes the bubbles and gives the glassy finish.
- 3 Skim off any surface foam. Cover the bowl with a plate or foil so condensation does not drip onto the surface and pit it.
- 4 Steam over low heat for 10 to 12 minutes, until just set with a slight wobble in the centre. A gentle steam is essential; high heat makes it bubble and turn spongy.
- 5 Scatter over the softened goji, finish with a few drops of sesame oil and light soy, and serve warm.
Notes and substitutions
- The liquid to egg ratio matters more than anything else. Around 1.5 parts warm liquid to 1 part beaten egg gives the classic silk; more liquid makes it softer still.
- Keep the heat low and lift the lid a crack, or leave a chopstick under it, so the steam stays gentle.
- A spoon of cooked minced pork or a few prawns set into the custard turns it into a light meal.
Before you cook this
- Make sure the egg is fully set, with no runny liquid, since undercooked egg is best avoided while recovering.
Common questions
Can I eat steamed egg in the first week?
Yes. It is one of the dishes most often recommended for the early days precisely because it is warm, gentle and easy to digest, unlike the richer sesame oil and rice wine dishes that are usually held back to the later weeks.
Why did my custard turn out full of holes?
Almost always too high a heat. Steaming hard makes the egg bubble and set spongy. Keep the steam low and gentle, cover the bowl, and it will set smooth.
What liquid should I use?
Warm water works, but a light chicken stock makes it more savoury and nourishing. Whatever you use, warm it first so it does not cook the egg before it reaches the steamer, and keep to roughly 1.5 parts liquid to 1 part egg.
