Tian Jiu Niang Recipe

Rinse and soak rice

Rinse 2 cups glutinous rice under cold water until the rinse water runs mostly clear. Drain and place in a bowl with 4 cups water. Soak at room temperature for 4–6 hours or overnight for best texture.

Steam the rice

Drain the soaked rice thoroughly. Transfer rice to a heatproof dish or bamboo steamer lined with cheesecloth. Steam over boiling water for 30–40 minutes until grains are translucent and tender but still hold shape. Check halfway and fluff gently to ensure even cooking.

Cool the rice

Spread the steamed rice on a clean, shallow tray to let it cool to about 30–35°C (warm but not hot). Stir occasionally to release steam so it cools evenly. It's important the rice is warm, not hot, when you add the starter to avoid killing the yeast.

Prepare starter

If using traditional tian jiu starter (a powdered culture), dissolve 1 tsp in 2 tbsp boiled then cooled water (around 40°C). If using dry active yeast, dissolve 1 tsp in the same manner. Let bloom for 5–10 minutes until slightly foamy (yeast) or well-dispersed (starter).

Inoculate rice

Place the cooled rice into a clean, dry glass or ceramic fermenting container (avoid metal). Sprinkle the dissolved starter evenly over the rice and fold gently with a sanitized spatula or spoon until the starter is evenly distributed. Press the rice down lightly to make a compact layer, leaving some air gaps for fermentation gases.

Initial fermentation

Cover the container with a breathable lid (cheesecloth or a loose lid) to allow gas escape while keeping dust out. Place in a warm, stable location between 28–32°C (82–90°F). Let ferment for 24–36 hours; you should begin to see some liquid and a sweet, mildly alcoholic aroma. Check after 24 hours and gently stir once to distribute moisture.

Make sugar syrup

While the rice ferments (can be done just before finishing), combine 1 cup granulated sugar, 0.5 cup rock sugar (if using), 1 cup water and 1 tbsp thinly sliced ginger in a small saucepan. Bring to a simmer and stir until sugars dissolve. Simmer 2–3 minutes to infuse ginger, then remove from heat and cool to warm (not hot). Strain out ginger slices if desired.

Combine syrup with fermented rice

After 24–48 hours of fermentation (depending on desired sweetness and development), taste a small spoonful of the rice. When it has developed a pronounced sweet-sour, mildly alcoholic aroma and some liquid has formed between grains, pour the cooled sugar syrup evenly over the fermented rice. Use the syrup gradually and stir gently; the rice should be moist but not soupy. Add up to 0.5 cup boiling water if rice seems too clumpy to loosen it before stirring.

Secondary mellowing (optional)

Cover the container again and leave at room temperature for another 6–12 hours to let the flavors integrate and the rice absorb syrup. Refrigerate after desired flavor is reached to slow fermentation and chill the tian jiu niang for serving.

Adjust final seasoning

Taste the finished tian jiu niang and add up to 1 tsp salt if needed to balance sweetness. Stir gently to distribute.

Serve

Spoon chilled or room-temperature tian jiu niang into small bowls. Garnish with 2 tsp roasted sesame seeds and 2 tbsp chopped peanuts if desired. Consume within 3–5 days refrigerated; the product will continue to ferment slowly and grow more sour/winey over time.

Safety notes

Always use clean utensils and containers. If you see mold (fuzzy, colored colonies) or smell an off-putting rotten odor, discard the batch. Maintain warm but not hot fermentation temperatures to avoid growth of undesirable microbes.
