White Fungus and Papaya Sweet Soup | IDDSI Level 4 Recipe

IDDSI Level 4 (Pureed) | 15 minutes prep, 40 minutes cooking | Easy

White fungus and papaya sweet soup (雪耳木瓜糖水, syut yi muk gwa tong seui) is a beloved Cantonese nourishing dessert soup — the gelatinous quality of snow fungus (silver ear fungus) combines with the natural sweetness and silky texture of ripe papaya to produce a light, fragrant sweet soup traditionally associated with moistening the lungs and promoting skin health. Traditional recipes retain the papaya in soft chunks and the white fungus with some chew, placing them outside the safe range for IDDSI Level 4 diets. This adaptation fully cooks and blends the papaya into a smooth, particle-free puree meeting Level 4 Pureed requirements. White fungus is managed separately: either cooked until very soft and individually tested, or omitted to simplify texture management.

Ingredients (3–4 servings)

• 400g ripe papaya (peeled, deseeded, cut into chunks; use fully ripe fruit with orange-red flesh)
• 15g dried white fungus / snow fungus / yin er (soaked 2–3 hours; hard stem removed; torn into small florets)
• 1000ml water
• 40–60g rock sugar (adjust to taste)
• 15g wolfberries / goji berries (optional; soaked in warm water until soft; confirm texture individually before serving)
• 1 small pinch of salt (to balance sweetness)

Method

1. Soak the white fungus in cold water for 2–3 hours until fully hydrated and translucent. Remove and discard the hard yellowish stem at the base of each piece — it does not soften even with prolonged cooking. Tear the fungus into small florets.
2. Peel and deseed the papaya; cut into 3cm chunks. Use fully ripe papaya (skin mostly yellow, flesh yielding to gentle pressure) — underripe papaya is too firm and faintly bitter.
3. Combine 1000ml water and white fungus in a medium saucepan. Bring to the boil; reduce heat to low; cover and simmer 25 minutes until the fungus is completely transparent and very soft with no resistance.
4. Add papaya chunks; continue simmering over low heat for 15 minutes until completely soft (a chopstick should pierce the papaya with zero resistance).
5. Manage the white fungus: for fully Level 4-compliant texture, remove and discard the fungus before blending. If the fungus is very soft and the individual can safely manage it, retain some pieces and conduct a separate texture test.
6. Transfer the papaya and cooking liquid to a blender; blend on high speed for 60 seconds until completely smooth.
7. Pass through a fine-mesh sieve to remove any fibrous residue. Return to the saucepan; add rock sugar and salt; stir over low heat until sugar dissolves completely.
8. Add wolfberries (if using, fully soaked), simmer 5 minutes; confirm the berries are fully soft before serving, or strain them out to ensure Level 4 compliance.
9. Serve warm or cooled to room temperature.

Texture Test

IDDSI Level 4 (Pureed) confirmation: Spoon the papaya puree onto a plate and tilt — the puree should flow or slide slowly rather than running freely. Check by running between fingertips: there should be absolutely no particles, fibres or lumps. The puree should hold a shape briefly but begin to flow slowly under gravity.

If thicker texture is needed: Add a small amount of a suitable food thickener or a teaspoon of coconut flour; adjust until the puree holds shape on the plate without flowing — this corresponds to the denser end of Level 4 (Extremely Thick).

Safety Notes

⚠️ White fungus stem is non-negotiable — The hard central stem of dried white fungus remains fibrous even after prolonged cooking and blending. It must be removed entirely during the soaking step; the straining step provides a second safety check but is not a substitute for stem removal.

⚠️ Papaya ripeness — Underripe green papaya contains firm fibres and latex that do not break down fully during cooking. Always use fully ripe fruit with predominantly yellow-orange skin to ensure complete softening and a smooth blend.

⚠️ Wolfberry texture verification — Wolfberries are small but constitute solid particles if insufficiently soaked. Either soak thoroughly (minimum 15 minutes in warm water) and confirm softness by crushing between fingertips, or omit entirely for unambiguous Level 4 compliance.

⚠️ Serving temperature — Check temperature before serving; the thicker consistency retains heat longer and the surface temperature may be deceptively lower than the core. Aim for below 60°C.

Sourcing in Hong Kong

• Ripe papaya: Wet market fruit stalls; select papaya that is 70–80% yellow-skinned with slight give when pressed; fully yellow, very soft fruit produces an even smoother blend but has higher sugar concentration
• Dried white fungus (snow fungus / yin er 銀耳): Chinese herbal dried goods shops and supermarkets; choose white or pale yellow pieces without brown spots; higher-quality fungus releases more gel during cooking
• Rock sugar: Supermarket condiment aisle; traditional yellow crystal rock sugar (老冰糖) complements the delicate sweetness of papaya better than refined white sugar

Nutrition

Approximately 130 kcal per serving (200ml), 30g carbohydrate, 1g protein. Papaya is exceptionally rich in vitamin C, beta-carotene (provitamin A) and papain, a digestive enzyme that supports protein digestion — particularly relevant for elderly individuals with reduced gastric acid production. White fungus polysaccharides (tremella glucuronoxylomannans) are recognised in Chinese nutritional medicine for their moistening properties and are being studied for immune-modulating effects. The naturally sweet, aromatic character of this dessert soup tends to achieve good compliance in elderly care settings where appetite is frequently diminished.

Cultural Note

White fungus and papaya sweet soup occupies a special place in Cantonese wellness food culture, long classified as a 滋補 (zi bu) — nourishing — dish suitable for people of all ages, particularly women and the elderly, on account of its gentle, moistening qualities. It appears on the dessert menus of dim sum restaurants, herbal tea houses and family kitchens across Hong Kong. Presenting a Level 4-compliant version in care settings allows elderly residents with dysphagia to participate in the same dessert culture as their families — a straightforward act of inclusion that meaningfully supports both nutritional intake and psychological wellbeing.
