“A bowl of clear, trembling jelly set from ice-jelly seeds, drowned in brown sugar syrup with peanuts, raisins and sago.”
The bite
Spoon goes in and the jelly cleaves like cold glass — clear, almost weightless, the texture of a soft contact lens. Brown sugar hits first, then ginger warmth, then the crunch of peanuts and the chew of raisins underneath. It's eaten in summer at hutong-side stalls in Lijiang and Chengdu both. If the jelly tastes of anything besides cold water and syrup, it sat too long or had too much lime.
Where it comes from
The seeds come from Nicandra physalodes, a wild lantern-fruit plant common across southwest China; people in Lijiang were rubbing them in cold mountain stream water for refreshment long before the dish reached Sichuan, where Chengdu's street vendors made it famous. Both regions claim it. The Yunnan version stays closer to the original — fewer toppings, sweeter syrup, a piece of raw ginger in the pot.
What makes it work
The setting agent is the trick: the polysaccharides in the seed coat (mostly pectin-like polygalacturonans) only gel in the presence of divalent calcium ions, which is why a pinch of food-grade lime water (calcium hydroxide) is mandatory. Skip it and you get cloudy water; add too much and the jelly turns chalky and tastes faintly of plaster. 2 grams to 1.5 liters is the line.

Place 30g ice-jelly seeds (冰粉籽, Nicandra physalodes) in a clean cloth bag. Submerge in 1.5L cold spring or filtered water at 20°C.
- 28 min
Knead the bag underwater for 8 minutes until the water turns slightly cloudy and viscous — a clear gel is releasing from the seeds. Discard the bag.
- 32 min
Whisk in 2g food-grade calcium hydroxide (石灰水) dissolved in 30ml water. The liquid will start to set within 90 seconds. Pour gently into a flat tray.
- 4180 min
Refrigerate at 4°C for at least 3 hours, ideally 4, until firm enough to hold a spoon mark but still wobbling.
- 56 min
Make brown sugar syrup: simmer 100g dark brown sugar with 80ml water and a small piece of crushed ginger for 4 minutes until thick. Cool.
- 64 min
Cube the jelly with a spoon directly into bowls. Pour syrup over, scatter chopped peanuts, raisins, cooked sago and a little shredded coconut. Serve cold.
