What Is Snow Fungus?
If you have ever walked through the dried goods aisle of a Chinese herbal shop and spotted what looks like a pale, crinkled snowflake that blossoms into a glassy, honeycomb-like cloud when rehydrated — you have met snow fungus (Tremella fuciformis, or 银耳 yín ěr — "silver ear"). Known also as white fungus or tremella, this gelatinous mushroom has been treasured in Traditional Chinese Medicine (TCM) for centuries as a premier beauty and longevity food.
Unlike the savoury mushrooms you might toss into a stir-fry, snow fungus is prized for its delicate, almost neutral flavour and its remarkable ability to absorb and hold moisture. When simmered into a sweet dessert soup with goji berries and red dates, it transforms into a silky, comforting tonic that feels as nourishing as it tastes.
Snow Fungus in Traditional Chinese Medicine
A Supreme Yin Tonic
In TCM, snow fungus is classified as a yin tonic — a food that nourishes the body's foundational moisture and cooling energy. It enters the Lung and Stomach meridians, which means it is traditionally believed to support respiratory health and digestive hydration. Its nature is neutral to slightly cooling, and its flavour is sweet, which in TCM correspond to harmonising and moistening qualities.
Yin deficiency — a pattern marked by dryness, thirst, night sweats, heat sensations, and a dry cough — is especially common during autumn, in heated indoor environments, and as we age. Snow fungus is considered one of the gentlest and most effective ways to supplement yin without overwhelming the digestive system.
From Qing Dynasty Beauty Manuals to Modern Kitchens
The beauty benefits of snow fungus were so esteemed that legend has it the concubines of the Qing Dynasty consumed it daily as part of their skincare regimen. Empress Dowager Cixi — a famously beauty-conscious ruler — was said to rely on a daily bowl of snow fungus soup to maintain her famously luminous complexion well into old age. While we cannot verify every detail of these accounts, the tradition of snow fungus as a "beauty tonic" runs deep in Chinese culinary and medicinal culture.
Modern research has found that snow fungus is rich in tremella polysaccharides, a type of water-soluble fibre that forms a gel-like substance — remarkably similar in molecular structure to hyaluronic acid. These polysaccharides are believed to help the skin retain moisture, which aligns beautifully with the traditional understanding of snow fungus as a hydrating, yin-nourishing food.
Complete Recipe: Snow Fungus and Goji Berry Dessert Soup
This dessert soup — known in Chinese as bīng táng yín ěr (冰糖银耳, "rock sugar silver ear") — is a staple of Cantonese tong sui (sweet soup) tradition. It is simple to prepare, forgiving of substitutions, and deeply satisfying as a warm dessert or a restorative breakfast.
Ingredients
- 15 g dried snow fungus (about 1 small handful or 1 whole dried head)
- 10 g goji berries (枸杞, gǒu qǐ) — about 1 heaped tablespoon
- 5 red dates (红枣, hóng zǎo) — pitted and sliced
- Rock sugar (冰糖, bīng táng) — to taste, about 20–30 g (substitute: coconut sugar or honey)
- 1.2 L water (about 5 cups)
- 1 pear (optional, but recommended) — peeled, cored, and cut into bite-sized chunks
Optional additions: 15 g lotus seeds (dried, soaked), 10 g dried lily bulb (百合, bǎi hé), or a small piece of dried tangerine peel (陈皮, chén pí) for a subtle citrus note.
Step-by-Step Instructions
- Soak the snow fungus. Place the dried snow fungus in a large bowl and cover with cool water. Soak for 30–60 minutes, or until fully softened and expanded to 3–4 times its original size. Trim away the hard yellow base at the centre and tear or chop the fungus into bite-sized pieces.
- Rinse the goji berries and red dates. Briefly rinse the goji berries and red dates under cool water. Pit the red dates and slice them into strips — this helps release their sweetness into the soup.
- Combine and simmer. In a medium pot, add the prepared snow fungus, red dates, and water. Bring to a boil over high heat, then reduce to a gentle simmer. Cover and cook for 40–50 minutes, stirring occasionally. The soup will gradually become thicker, silkier, and slightly gelatinous as the snow fungus releases its natural polysaccharides.
- Add the pear (if using). After 40 minutes, add the pear chunks and continue simmering for another 10 minutes. The pear adds natural sweetness and additional lung-moistening properties.
- Add goji berries and rock sugar. Add the goji berries and rock sugar in the final 5 minutes of cooking. Stir gently until the sugar dissolves. Goji berries should be added late to preserve their bright colour and delicate flavour.
- Serve warm or at room temperature. Ladle into bowls and enjoy warm. This soup can also be served chilled — it will set into a light, jelly-like consistency that is refreshing in warmer months.
Variations to Explore
Snow Fungus with Pear and Almonds
For an extra lung-nourishing version, add 10 g of blanched almonds (南杏, nán xìng) along with the pear. The combination of snow fungus, pear, and almonds is a classic TCM trio for dry coughs and seasonal dryness.
Snow Fungus with Lotus Seeds and Lily Bulb
Lotus seeds (莲子, lián zǐ) and dried lily bulb (百合, bǎi hé) are both calming, yin-nourishing ingredients. Soak 15 g of lotus seeds separately for 2 hours, then add them at the start of simmering with the snow fungus. Add the lily bulb in the final 15 minutes. This version is especially nice in the evening — it is traditionally believed to support peaceful sleep.
Who Should Eat Snow Fungus Dessert Soup?
Snow fungus dessert soup is suitable for most people, but it is especially beneficial if you recognise any of these signs of yin deficiency or dryness:
- Dry, dull, or dehydrated skin that does not improve with moisturiser alone
- Dry cough or a scratchy throat, especially in autumn or in air-conditioned environments
- Constant thirst or a preference for cold drinks
- Constipation with dry, hard stools
- Feeling "heated" — hot flashes, night sweats, or a sensation of heat in the palms and soles
- Recovery from illness, especially respiratory infections that leave the lungs feeling dry
Because snow fungus is neutral and mild, it can also be enjoyed as a general wellness food. Many families in China serve it weekly as a simple, nourishing dessert — comfort food that happens to be good for you.
Buying and Storing Snow Fungus
What to Look For
Dried snow fungus is widely available in Asian grocery stores, herbal shops, and online. Look for specimens that are a pale ivory or light golden colour — uniformly light, without dark spots or discolouration. The pieces should be dry, crisp, and lightweight. Higher-quality snow fungus is sold in whole heads rather than broken fragments, as the whole heads tend to retain more of their gelatinous properties.
How to Store
Keep dried snow fungus in an airtight container in a cool, dark, dry place. It will keep for 6–12 months. Once rehydrated, use it within 24 hours and store it in the refrigerator submerged in water. Do not freeze rehydrated snow fungus — the texture becomes mushy upon thawing.
Preparation Tips
Do not skip the soaking step. A thorough soak (30–60 minutes in cool water) is essential for achieving the signature silky, gelatinous texture. Some cooks also briefly blanch the soaked snow fungus in boiling water for 1–2 minutes to remove any residual earthy scent, though this is optional. Always trim and discard the hard yellow base at the centre of each head — it does not soften during cooking.
Safety Notes and Considerations
Snow fungus is generally recognised as safe for most people when consumed as a food. However, a few considerations are worth noting:
- Cold constitution. If you tend to feel cold easily, have cold hands and feet, or experience loose stools, enjoy snow fungus in moderation. Its neutral-to-cooling nature may aggravate these patterns. Adding ginger slices or warming red dates can help balance the effect.
- Dampness and digestive weakness. TCM recognises that very gelatinous, sticky foods can be difficult to digest for people with dampness or weak spleen qi. If you have a feeling of heaviness, bloating, or a thick tongue coating, limit your portion size or pair the soup with a small piece of dried tangerine peel to aid digestion.
- Pregnancy and nursing. Snow fungus is generally considered safe during pregnancy in food amounts, but as with any dietary change, consult your healthcare provider. The high polysaccharide content means it absorbs a lot of water — stay well hydrated.
- Blood sugar. If you are managing diabetes or blood sugar concerns, reduce or omit the rock sugar and use a small amount of monk fruit sweetener (luo han guo) instead, which has a neutral effect on blood glucose.
Frequently Asked Questions
How often can I eat snow fungus dessert soup?
Snow fungus dessert soup is mild enough for regular consumption. In TCM tradition, it is often enjoyed 2–3 times per week during dry seasons (autumn, winter, or dry indoor-heated months). For general maintenance of yin and hydration, once a week is plenty. Those with pronounced dryness or yin deficiency may benefit from more frequent use, but listen to your body — if you experience loose stools or a feeling of heaviness, reduce frequency.
Is snow fungus good for lung health?
Yes. In TCM, snow fungus is classified as a lung meridian tonic. It is traditionally believed to nourish lung yin, moisten dryness, and help calm dry coughs. Its high concentration of polysaccharides may also support immune function. While it is not a treatment for respiratory illness, many people find it soothing during dry coughs, seasonal dryness, or when recovering from a cold.
Who should not eat snow fungus?
Snow fungus is generally well-tolerated, but those with a cold or yang-deficient constitution — who tend to feel cold, have poor circulation, or experience loose stools — should consume it in moderation, as it is neutral-to-cooling. People with digestive weakness or dampness (feeling of fullness, heavy limbs, thick tongue coating) may also wish to limit intake or pair it with ginger or red dates. As always, consult a qualified TCM practitioner if you have concerns about your constitution.
Can I make snow fungus dessert soup in a slow cooker?
Absolutely. A slow cooker (crockpot) works beautifully for this dessert soup. Soak the snow fungus as directed, then add all ingredients — including the rock sugar — to the slow cooker with fresh water. Cook on low for 4–6 hours or on high for 2–3 hours. The low, steady heat helps the snow fungus release its full gelatinous texture. Add goji berries and pear (if using) during the last 30 minutes to preserve their shape and flavour.
