Ultra-Smooth Steamed Egg Custard | IDDSI Level 3 Recipe
IDDSI Level 3 (Liquidised) | 25 minutes | Easy
Standard steamed egg custard (蒸水蛋) — made at a 1:1.5 egg-to-liquid ratio — reaches IDDSI Level 4 (Pureed). This Level 3 version uses a higher liquid ratio (1:2.5 to 1:3) to produce a much thinner, softer set that flows when tilted rather than holding a firm shape. The result is a barely-set, silky egg liquid that can be spooned or poured from a shallow bowl — suitable for patients who cannot manage even the softest solid foods. High protein content makes it an efficient dysphagia-safe meal component.
Ingredients (2 servings)
- 2 large eggs
- 250–300ml warm (not boiling) stock or water (approximately 1:2.5 ratio)
- ¼ teaspoon salt
- ½ teaspoon light soy sauce
- ½ teaspoon sesame oil (for topping — optional)
- 1 teaspoon light soy sauce (for serving — optional)
Note on liquid: Warm (approximately 60°C) rather than cold liquid gives a finer, smoother set. Chicken stock produces a more flavourful result than water. For a purer, sweeter custard, use water with a small pinch of salt.
Method
- Crack the eggs into a bowl. Beat gently with chopsticks — do not over-whisk (air bubbles create a rough, pitted surface rather than the desired silky finish).
- Add the salt and soy sauce. Gradually pour in the warm liquid while stirring gently.
- Pass the egg mixture through a fine mesh sieve into a shallow steam-safe bowl. This removes any chalaza or egg fragments that would create texture irregularities.
- Cover the bowl tightly with cling film or a plate to prevent condensation droplets falling onto the surface during steaming (which would create pitting).
- Place the bowl in a steamer over medium-low heat. The water should be simmering but not at a rolling boil — high heat causes bubbling and a rough surface.
- Steam for 12–15 minutes. The custard is ready when it is just barely set — it should still wobble when gently shaken, and when a spoon is tilted, the custard should flow slowly like a very thick liquid. It should NOT hold the impression of the spoon.
- Remove from steamer. Uncover gently. Add a drizzle of sesame oil and light soy sauce if desired.
- Level 3 check: Tilt the bowl slightly — the custard should slowly flow and level out. It should not hold any solid shape. If the custard has set too firm (does not flow), increase the liquid ratio to 1:3 in the next batch.
Texture Test
- Tilt test: When the bowl is gently tilted, custard flows slowly — consistent with Level 3 (Liquidised).
- Spoon drip test: A spoonful poured from height flows continuously without breaking into separate drops.
- No visible lumps or egg white strands after sieving.
Serving
Serve immediately, at body temperature. Spoon gently from the bowl — do not attempt to unmould or plate separately. The level 3 custard is fragile and will not hold its shape when moved.
For patients with additional flavour preferences, a small amount of diluted oyster sauce or mushroom sauce can be drizzled on top without affecting texture (add after steaming, not before).
Why This Differs from Level 4 Custard
| Level 4 Custard | Level 3 Custard | |
|---|---|---|
| Egg:liquid ratio | 1:1.5 | 1:2.5 to 1:3 |
| Texture when cold | Firm set, holds shape | Barely set, flows |
| Spoon test | Holds spoon impression | Does not hold impression |
| IDDSI use | Pureed diet | Liquidised diet |
Caregiver Notes
The Level 3 custard will firm up slightly as it cools. For consistent Level 3 compliance, serve within 5 minutes of removing from the steamer. Do not refrigerate and reheat — the texture changes significantly. Make fresh in small batches as needed.
This recipe can be scaled easily: each large egg requires approximately 70–90ml warm liquid for Level 3 consistency. Adjust total volume based on the patient’s intake capacity.
