Steamed Egg, Chinese (Zhengdan)

⭐ This is the reference recipe for the whole dive. Get this right and every other steamed egg on the site is a variation on it.

Chinese steamed egg — 蒸蛋 zhengdan, or 水蛋 shui dan, “water egg” — is eggs, warm water, salt and nothing else, steamed gently until it sets into something with the texture of a very soft panna cotta. A spoon should glide through it without resistance and the surface should be a flat, unbroken mirror.

🔴 The ratio is the recipe. 1.5 parts liquid to 1 part egg, by weight. Everything else is technique.

⚠ Weigh the eggs. “Three large eggs” covers a 20 g spread, and that is the difference between silky and rubbery. Crack them into a bowl, weigh, multiply by 1.5, add that much warm water. This one change fixes most of the inconsistency people blame on their steamer.

Ingredients

• 3 large eggs (about 150 g out of the shell — weigh them)
• 225 g warm water, or light chicken stock (1.5× the weight of the eggs)
• 1/4 tsp salt
• To finish
• 1 tsp light soy sauce
• 1/2 tsp toasted sesame oil
• 1 scallion, green part only, finely sliced

Directions

1. Crack the eggs into a bowl and weigh them. Multiply that number by 1.5 — that is how much water you need. Warm the water to about body temperature; ⚠ cold water sets unevenly and hot water cooks the egg into lumps while you stir.
2. Beat gently with chopsticks or a fork until uniform. 🔴 You are combining, not aerating. A whisk at speed puts air in, and every bubble becomes a hole.
3. Stir in the salt and the warm water.
4. ⭐ Strain through a fine sieve into your serving dish. Fifteen seconds, and it is the highest-return step in the dish — it catches the chalazae and any unmixed white.
5. Let it stand a minute and skim the foam, or drag a paper towel across the surface.
6. Cover the dish — foil, a lid, or a plate. 🔴 Not optional. Condensation dripping off the steamer lid pocks the surface and you will see every single drop.
7. Bring the steamer water to a boil, then turn it down to a bare simmer before the dish goes in. If the lid is rattling it is too hot.
8. Steam 12 minutes for a shallow dish this size. It is done when the centre wobbles as a unit, like set jelly, rather than sloshing.
9. Pull it a touch early — ⚠ it keeps cooking in the hot dish for another minute or two.
10. Uncover, thread the soy sauce and sesame oil over the top, scatter the scallion. Serve immediately, with rice.

Notes

⭐ A shallow, wide dish beats a deep one. It cooks faster and more evenly, and it is what makes the flat restaurant presentation possible. A deep bowl of this needs closer to 18 minutes and the outside will be firmer than the middle.

🔴 If it comes out honeycombed, the heat was too high — not the time too long. Above about 85 °C the egg proteins contract and squeeze their water back out, it flashes to steam, and you get holes. Turn the burner down further than feels reasonable.

Stock instead of water makes it markedly better and is what most restaurants do. Light chicken stock, or the soaking water from dried shiitake, or — crossing into Japanese territory — dashi.

⭐ Lay a chopstick across the pot under the lid. It vents a little steam and drops the temperature a few degrees. Cheapest trick in the dive.
