Putaojing Cold Rice Jelly is the signature summer sweet of Shuanghe Town, Changning County, Yibin — made from local Guizhao indica rice ground on a stone mill and cooked in water from the thousand-year-old Grape Well (葡萄井). A thread of lime water sets the slurry as it cooks; the finished paste is ladled into clay bowls and submerged in cold flowing spring water for four hours until the jelly is perfectly chilled and firm. Unmolded and sliced into diamond shapes, then drenched in cold brown sugar syrup, it delivers a texture somewhere between silken tofu and panna cotta — clean, white, and barely there on the tongue. The well water's mineral sweetness underpins the whole.
Shuanghe Town has been settled for over 1,300 years. The spring now called Grape Well (葡萄井) was recorded as early as the Southern Song dynasty in Wang Xiangzhi's geographic text Yudi Jisheng, which praises the water as supremely sweet (极甘). At the time the spring was known as Jiayu Spring (嘉鱼泉). During the Qing Tongzhi reign (1862–1874), county official Xi Shuxin built a Dragon King Temple at the site; enchanted by the spring's steady rising bubbles — each cluster resembling a bunch of grapes — he inscribed the stone archway with Grape Well, and the name has held ever since. The exact beginning of liangao-making from this spring is undocumented, but a Qing Guangxu-era record by local scholar Du Deyu notes that 'great numbers come here to cool off, and the snack liangao is famous for its tender freshness,' placing the dish firmly in the late 19th century at the latest. The craft is listed in Yibin's intangible cultural heritage, with acknowledged inheritors including Liu Junhong, Zeng Jizong, and Wang Quan; a dedicated Liangao Street of more than ten shops has formed around the well.
The jelly is unmolded whole — snow-white, faintly trembling — then sliced into diamond shapes and flooded with cold brown sugar syrup. The first sensation is a clean cold shock on the tongue; then the texture vanishes almost before it registers: not springy like panna cotta, not yielding like soft tofu, but something between the two — a barely-there silkiness that leaves only sweetness behind. The brown sugar brings a thread of caramel warmth; the rice slurry adds a faint, clean fragrance. The well water's mineral note runs underneath, present but elusive. Most Sichuan people remember this not for its complexity but for a single word — cool (凉) — the most effective antidote to a Shuanghe summer.
The set depends on two successive steps. First, fully gelatinizing the rice slurry: as the milled indica rice paste meets boiling water, starch granules burst, absorb water, and unfold into an interlocking polymer network — a translucent, flowable gel. Second, lime water (calcium hydroxide solution) crosslinks the network: calcium ions form weak bonds with the hydroxyl groups on starch chains, stiffening the gel on cooling so it holds its shape cleanly without collapsing. The principle echoes gypsum setting tofu, but the substrate is rice starch rather than soy protein, and the result is finer-textured. Guizhao rice is a high-amylose indica variety; amylose molecules recrystallize more tightly on cooling than the branchy amylopectin dominant in glutinous rice, giving the jelly its firm, non-sticky bite rather than a mochi-like softness. Stone-milling breaks rice cells more finely and uniformly than machine grinding, which is why the traditional method yields a distinctly smoother jelly.
Variations
The traditional form comes with cold brown sugar syrup only — the version most old Shuanghe shopkeepers still defend as the sole legitimate one. Vendors along the well's Liangao Street have since expanded to around thirty flavors: osmanthus honey, watermelon juice, mango, passion fruit, and a spicy seasoned variant. A popular local add-on tops the brown sugar syrup with crushed peanuts and sesame. For longtime residents, anything beyond plain cold brown sugar syrup is spectacle rather than substance.

Ingredients
Serves 4How it's made
9 steps · 1 hour active + 14 hours waiting
- 1660 min
Rinse the indica rice and soak in cold water for 10 to 12 hours, until the grains soften enough to crumble to powder between your fingertips.
- 210 min
Drain the soaked rice and grind in small batches on a stone mill — or in a high-speed blender as a substitute — adding just enough fresh water to keep things moving, until you have a very fine, smooth slurry with no grit.
- 35 min
Dissolve a small amount of food-grade lime in water, let settle for 10 minutes, then carefully pour off the clear lime water from above the sediment; discard the sediment.
- 45 min
Measure out 3 parts spring or filtered water and bring to a rolling boil in a heavy-bottomed pot.
- 515 min
Stir the settled rice slurry to recombine, then pour it in a slow, steady stream into the boiling water while stirring constantly with a wooden paddle; reduce to medium heat and stir without stopping.
Watch outPour the slurry into boiling water in a thin steady stream while stirring nonstop — dump it in and it seizes into lumps that never smooth out.
- 65 min
After about 15 minutes, when the slurry is opaque and the edges begin to pull away from the pot, drizzle in the clear lime water in a thin stream while continuing to stir; cook 2 more minutes until the paste holds its shape on a spoon.
Watch outCook until the paste holds its shape on the spoon before you add the lime water — too loose and the jelly won't set clean; too far and it turns rubbery.
- 7240 min
Working quickly, ladle the hot paste into clay bowls or small round bowls and smooth the surface; let cool at room temperature, then transfer bowls to a basin of cold water or submerge in flowing cold water for at least 4 hours until fully set and thoroughly chilled.
Watch outChill it thoroughly in cold water until fully firm before unmolding — a barely-set jelly collapses the moment you turn it out.
- 810 min
Make the syrup: dissolve brown sugar in a small amount of hot water, stir until smooth, then refrigerate until cold.
- 95 min
Run a thin knife around each bowl's edge, invert onto a plate, and slice the jelly into diamond-shaped pieces; pour the cold brown sugar syrup generously over top and serve immediately.
