Black Glutinous Rice Pudding | IDDSI Level 4 Recipe
IDDSI Level 4 (Pureed) | 60 minutes (plus soaking) | Easy | High Antioxidants
Black glutinous rice (黑糯米) is a nutritionally exceptional whole grain — its deep purple-black colour comes from a high concentration of anthocyanin antioxidants in the outer bran layer, the same class of phytonutrients responsible for the health benefits of blueberries, red cabbage, and purple sweet potato. In traditional Chinese medicine, black glutinous rice is classified as a 補血 (blood-tonifying) ingredient, associated with nourishing the kidneys and liver. As a dessert pudding, black glutinous rice cooked with coconut milk and ginger produces a creamy, deeply flavoured sweet dish that is popular across Southeast Asia (particularly in Thailand and Malaysia, where ‘khao niew dam’ is a beloved street dessert). For IDDSI Level 4 (Pureed), the cooked rice is blended with its coconut cooking liquid until smooth and creamy — spoonable, mound-holding, and yielding with minimal fork pressure.
Ingredients (4 servings)
Black glutinous rice pudding:
- 120g black glutinous rice (黑糯米), soaked in cold water for at least 4 hours or overnight
- 400ml water
- 200ml coconut milk (full-fat, from a can)
- 40g palm sugar or light brown sugar (adjust to taste)
- 2 slices fresh ginger
- Pinch of salt
Coconut topping (optional but traditional):
- 80ml coconut cream (thicker than coconut milk — from the top of an unshaken can)
- Pinch of salt
Method
- Drain the soaked black glutinous rice. The soaking water will be a deep purple — this can be reserved and used as part of the cooking liquid to retain the anthocyanins, or discarded.
- Place the rice in a pot with 400ml fresh water and the ginger slices. Bring to a boil, then reduce to a very low simmer, cover with a tight lid, and cook for 35–40 minutes until all the water has been absorbed and the rice is completely soft — the grains should be fully swollen and tender, crushing easily between fingers.
- Remove the ginger slices. Add the coconut milk, sugar and salt to the cooked rice. Stir over low heat for 5 minutes until the sugar dissolves and the mixture is evenly creamy.
- Transfer the entire mixture to a blender. Blend on high speed for 2–3 minutes until completely smooth. The result will be a deep purple-grey creamy pudding. Pass through a fine-mesh sieve if a particularly smooth result is desired.
- Level 4 consistency check: Spoon onto a plate — it should form a soft, rounded mound that holds its shape but slumps gently at the edges. It should not flow freely (that would be Level 3). If too runny, return to a pot and cook over medium-low heat, stirring continuously, for 3–5 minutes to thicken. If too thick, blend in a small amount of warm coconut milk.
- If using the coconut topping: whisk together the coconut cream and salt until slightly thickened. Drizzle over the portioned pudding just before serving.
Texture Test
Fork test: Passes Level 4 — a spoonful placed on a fork holds a soft mound; it does not flow off the fork but falls with gentle pressure.
Pressure test: A portion pressed between two fingers yields smoothly — no grainy particles, no rubberiness.
Consistency: Uniformly smooth and creamy throughout — no whole or partially intact rice grains, no coconut fibre pieces.
Safety Notes
⚠️ Sieve after blending — black glutinous rice bran can sometimes leave small fibrous particles even after thorough blending. Pass through a fine-mesh sieve for residents with severe dysphagia.
⚠️ Coconut topping consistency — the coconut cream drizzle should be pourable and liquid, not thick or clotted. Check that it does not create a discrete separate layer that is thicker than Level 4 when added to the pudding.
⚠️ Ginger removal — ensure all ginger slices are removed before blending. A piece of ginger in the blended pudding is not appropriate for Level 4.
⚠️ Temperature — serve warm (not hot) at approximately 55–65°C. The pudding retains heat — test before serving.

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 220 kcal per serving, 4g protein, 8g fat (from coconut), 36g carbohydrates. Black glutinous rice is significantly richer in anthocyanin antioxidants than white or brown rice. Anthocyanins are associated with reduced cardiovascular disease risk, improved glycaemic response, and neuroprotective effects in ageing populations. The full-fat coconut milk adds medium-chain triglycerides (MCTs), which are easily metabolised for energy and may support cognitive function. This dessert is moderately calorie-dense and suitable for residents with poor appetite or undernutrition.
Cultural Note
Black glutinous rice desserts are beloved across Southeast Asia and southern China. In Hong Kong, 黑糯米糊 (black glutinous rice paste) is a popular tong sui (sweet soup) found at dessert shops and traditional sweet soup restaurants. For Cantonese elderly residents, it evokes the warmth of late-night dessert shop visits, the smell of coconut and warm grain, and the particular satisfying sweetness of a well-made tong sui after a family dinner.
Variation
- To adjust to Level 3 (Liquidised): Add 100ml warm coconut milk and blend for a further minute. The mixture should flow freely from a tilted spoon.
- Taro combination: Replace 40g of the black glutinous rice with equal weight of cooked taro. The result has a sweeter, starchier flavour and a slightly lighter purple colour.
- Storage: The pudding can be made ahead and refrigerated for up to 3 days. It thickens considerably when cold. Reheat gently with a splash of coconut milk, stirring until smooth, and recheck consistency before serving.
