Steamed Zucchini & Egg | IDDSI Level 4 Recipe

IDDSI Level 4 (Pureed) | 20 minutes | Easy | Vegetarian

蒸節瓜蒸蛋 (steamed zucchini egg) combines two of the lightest, most easily digestible ingredients in the Cantonese soft food repertoire. Zucchini (節瓜 / 翠玉瓜) has one of the highest water contents of any vegetable and becomes completely soft when steamed, blending seamlessly with egg to create a pale green, light vegetable-egg set. Steamed in a water bath, the mixture sets to a smooth Level 4 consistency: soft, yielding, and easy to consume in a small volume. This is a lighter, lower-calorie alternative to pure egg custard, suitable for residents who find rich, egg-only preparations too heavy.

Ingredients (2 servings)

Main:

Seasoning:

Method

  1. Steam zucchini pieces for 10 minutes until completely tender and soft. Remove excess water by pressing gently in a strainer.
  2. Place steamed zucchini in a blender; blend briefly with 50ml stock until smooth.
  3. Beat eggs thoroughly; combine with remaining 100ml warm stock, soy sauce, salt and white pepper. Mix until uniform.
  4. Combine blended zucchini puree with egg mixture; mix well.
  5. Pass through a fine-mesh strainer into a clean heatproof bowl to ensure smoothness.
  6. Cover tightly with cling film. Steam over medium-low heat for 12–14 minutes until just-set (the surface should barely jiggle).
  7. Drizzle with sesame oil. Serve immediately.

Texture Test

IDDSI Level 4 (Pureed) confirmation: Press the surface gently with the back of a spoon — yields immediately and slowly collapses; no rebound. No zucchini pieces or egg curds visible. Tilt the bowl slightly — the set mixture stays in place but the surface moves very slowly at the edges. Pale green colour throughout.

Safety Notes

Water bath requirement — steam over medium-low heat only. High heat will over-cook the egg, producing bubbles, pitting and a rubbery texture inconsistent with Level 4.

Zucchini moisture — zucchini releases water during cooking; squeeze out excess after steaming to prevent the mixture from becoming too watery to set.

Serve immediately — egg-zucchini custard deteriorates quickly in quality; do not hold for more than 20 minutes after steaming.

Sourcing Outside Hong Kong

For international care kitchens and home cooks outside Hong Kong, Cantonese ingredients are widely available at East and Southeast Asian grocery stores:

Zucchini / courgette: universally available at any supermarket.

If a specific ingredient is unavailable in your region, the recipe notes alternative substitutions in the Ingredients section. For dishes requiring fresh Cantonese-specific ingredients (e.g. preserved century egg, fresh rice noodle rolls), check with your local East Asian grocer before substituting — texture compliance for IDDSI levels may require specific products.

Nutrition

Approximately 100 kcal per serving, 9g protein, 6g fat, 3g carbohydrates. This is one of the lowest-calorie Level 4 vegetarian preparations, suitable for residents on calorie-restricted diets. Zucchini is high in water content and provides B vitamins and potassium. Eggs contribute complete protein, choline and fat-soluble vitamins.

Cultural Note

Steamed egg preparations (蒸蛋) are a cornerstone of Cantonese soft food culture, with a history going back centuries. Adding vegetables to steamed egg is a natural extension of this tradition — practical, nourishing and gentle. 蒸節瓜蒸蛋 takes two of the most common Cantonese kitchen ingredients and combines them in a form that is simultaneously clinical and culturally grounded, light and comforting.
