Aiyu is a plant-based jelly ingredient unique to Taiwan. The seeds of the aiyu fruit, which are rich in natural pectin, are rubbed by hand in cold water until the pectin dissolves, then left to set into a translucent, springy natural jelly. Cut into pieces and placed in lemon syrup or honey water, it is the representative street dessert for cooling down in a Kaohsiung summer. The handmade aiyu ice at veteran shops around Liuhe Night Market and in Yancheng's old commercial district is in a completely different category from the industrial version sold in convenience stores — the light, springy quality of natural jelly is the core experience of this dessert.
What is aiyu ice
Aiyu zi is the fruit of a fig-family plant native to Taiwan. After the fruit is dried, the pectin-rich seeds inside are scraped out, wrapped in a cloth bag, and kneaded repeatedly in cold water until the pectin dissolves, then left to set naturally for 20 to 30 minutes. The finished jelly is a pale yellow, semi-translucent color with a soft, springy texture more delicate than agar or gelatin-based artificial jellies. It is served with freshly squeezed lemon juice, plain syrup, or passion fruit juice; summer is the most common season, though it can also be enjoyed with brown sugar ginger syrup.
Aiyu zi, the raw ingredient, is mostly collected from mountainous areas in central and southern Taiwan; it is a native plant, and commercial harvesting was already recorded during the Japanese colonial period. Because Kaohsiung's climate is hot, demand for cooling drinks and desserts is high, and aiyu ice stalls at Liuhe Night Market and the Yancheng old commercial district have been running for decades. The difference between handmade aiyu and industrial packaged aiyu lies in the pectin content and the texture of the set jelly — the hand-rubbed version is delicate and refreshing, the industrial version thicker and with a more artificial gel-like texture. Veteran shops consistently uphold the hand-rubbing process.
How to eat it like a local
Local knowledge
Verified context
- Aiyu zi is the fruit of a fig-family plant native to Taiwan, with its raw ingredient collected from mountainous areas of central and southern Taiwan; it is the representative dessert made from a Taiwan native ingredient.
- Veteran hand-rubbed aiyu ice stalls at Liuhe Night Market and the Yancheng commercial district in Kaohsiung have been operating for decades and are representative nodes of Kaohsiung's summer cooling food culture.
- There is a clear difference in pectin texture between hand-rubbed aiyu and industrial packaged aiyu; veteran stalls' commitment to the hand-rubbing process is the key quality marker.
Things to know before you go
- Some stalls advertise handmade aiyu but actually use industrial pre-made product. The way to tell: look at the surface of the jelly — hand-rubbed versions have slightly irregular edges, while the industrial version has a uniform, consistent shape.
- Aiyu jelly begins to weep and soften after takeout as temperature rises. It is best eaten on the spot; after twenty minutes of takeout time the texture has already changed noticeably.
- Aiyu ice stalls around Liuhe Night Market attract a lot of tourists and prices are relatively high; veteran shops in Yancheng's old commercial district are more reasonably priced and offer better value.
