A dense, translucent golden cake made for the Dragon Boat Festival — glutinous rice flour steeped in gardenia-fruit water and a touch of baking soda yields an amber-yellow kueh of gentle sweetness and faint cooling finish. Served cold, sliced with a string, dusted with white sugar: one of the most distinctive sweets in the Teochew 粿 calendar.
栀粿 belongs to the ancient Teochew 粿品 tradition — rice-based festival foods central to Chaoshan ancestor worship and seasonal observance. Its Dragon Boat Festival identity is well-documented in Chaoshan food ethnography: the gardenia tree (栀子, a member of the Rubiaceae family) was historically planted around Chaoshan homes for both medicinal and culinary use, its fruit pressed into service for festival-cake coloring. Unlike zongzi, which spread across China, 栀粿 is distinctly Teochew — a local summer answer tied to the Dragon Boat season's heat-clearing customs, as gardenia's properties against summer heat were noted in classical materia medica including Li Shizhen's Bencao Gangmu. Multiple Chaoshan food accounts record it as one of the canonical seasonal 粿 alongside 鼠麹粿 (Qingming) and 发粿 (New Year).
Sliced cold with a string — to preserve the yielding structure — then rolled in sugar: first cool and slightly elastic, then the gardenia's barely-there bitterness fades into neutral sweetness, leaving the throat-cooling sensation Teochew call 凉喉.
Dried gardenia fruit contains two main pigment classes: geniposide (a secoiridoid glycoside) and crocin (a carotenoid glycoside in the same family as saffron's yellow pigment). Aqueous extraction releases crocin readily, giving the liquid a saturated golden-yellow. Adding baking soda raises the pH, which stabilizes the pigments and slightly lowers starch gelatinization temperature. Glutinous rice starch is nearly 100% amylopectin (branched-chain), which gelatinizes fully at steaming temperatures into a dense, cohesive gel; upon cooling, partial starch retrogradation firms the texture while preserving chewiness. Serving cold slows further retrogradation, maintaining the characteristic golden translucency.
Variations
Some families substitute jasmine tea for plain water when extracting the gardenia color, adding a floral layer. A rice flour (non-glutinous) version produces a firmer, less chewy texture preferred by older eaters. Modern adaptations incorporate coconut milk for creaminess, though traditionalists hold that the original's cool, spare sweetness is the point.

Ingredients
Serves 8How it's made
7 steps · 20 min
- 120 min
Crack open 6–8 dried gardenia fruits; place in a bowl with 400 ml warm water and soak for 20 minutes until the liquid turns deep orange-yellow.
- 25 min
Strain the gardenia liquid through cheesecloth, pressing firmly; discard the solids. The liquid should be a clear, saturated golden-yellow.
- 35 min
Dissolve ½ tsp baking soda in the gardenia liquid, stirring until fully incorporated; the color will deepen slightly and stabilize.
Watch outStir the baking soda fully into the gardenia water — the alkali is what stabilizes and deepens that saturated golden-yellow.
- 410 min
Gradually pour the gardenia-soda liquid into glutinous rice flour, stirring constantly to form a smooth, lump-free batter; add sugar and mix well.
- 55 min
Pour batter into greased molds (small bowls or traditional ceramic kueh molds) to 90% capacity.
- 645 min
Steam over vigorously boiling water on high heat for 40–45 minutes; a skewer inserted into the center should come out clean.
Watch outSteam a full 40–45 minutes until a skewer comes out clean — underdone in the center stays wet and pasty.
- 730 min
Remove from heat and cool completely in molds for at least 30 minutes before unmolding. Slice with string thread, dust with white sugar, and serve cold.
