Taitung Ash Zongzi (Alkaline Rice Dumpling) | Taitung Signature Dish

Taitung's Dragon Boat Festival zongzi come in a golden-yellow color you rarely see elsewhere. That color comes from soaking glutinous rice in water steeped with ash from burned rice straw, which gives the grains a natural alkalinity. After steaming, the rice turns a semi-translucent amber. Dipped in brown sugar syrup or honey, the texture is springy and silky. Hakka settlers and Hokkien traditions fused in the traditional markets of this eastern city, leaving behind this unfilled, no-meat zongzi where the glutinous rice itself is the entire point.

What is Taitung Ash Zongzi

Taitung ash zongzi — also called alkaline zongzi — begins with burning rice straw or palm leaf sheaths to make ash, which is steeped in water and the clear upper liquid drawn off as lye (or food-grade alkali substitute in modern versions). Round glutinous rice is soaked in the lye water until the grains absorb the alkaline liquid and turn yellow, then wrapped in bamboo leaves and bound, held in shape with long bamboo pins, and boiled in a large pot for two to three hours. Once unwrapped, the finished zongzi is golden and semi-translucent, with a springy, elastic texture and no filling whatsoever. The unique mouthfeel of alkalized glutinous rice is the entire selling point; dipping it in brown sugar syrup or honey completes the eating experience.

Taitung City has received Hokkien and Hakka settlers since the Qing dynasty; both groups have a tradition of making alkaline zongzi, and the two blended in Taitung. The traditional markets along Gengsheng Road and Zhengqi Road are the most concentrated sales point for ash zongzi in the weeks before and after the Dragon Boat Festival, with most vendors operating as family-run businesses. They begin production about two weeks before Dragon Boat Festival each year and gradually wind down after the holiday. Geng Sheng Daily's annual Dragon Boat Festival special issues feature a comprehensive survey of local zongzi varieties and consistently document Taitung ash zongzi as an important branch of eastern Taiwan's zongzi culture.

How to eat it like a local

🍯

Dip in brown sugar syrup — the most traditional methodOlder Taitung locals simmer brown sugar with a little water into a thick syrup. Sliced ash zongzi dipped in that syrup balances the mild alkaline flavor of the rice with rich sweetness — the most traditional way to eat it.

🌿

Honey version is lighterUsing local Hualien or Taitung honey with the ash zongzi gives a finer, floral sweetness that suits those who find brown sugar too heavy.

📅

Only available around Dragon Boat FestivalTaitung ash zongzi is a seasonal festival food. The peak supply window runs from about two weeks before to one week after the Dragon Boat Festival on the lunar calendar. Authentic versions are very difficult to find at other times of year.

🏪

Look for vendors at traditional marketsThe traditional market vendors along Gengsheng Road and Zhengqi Road are the main places to buy them. Versions sold in tourist areas or supermarkets typically use food-grade alkali instead of rice-straw ash, which produces a slightly different flavor.

Visiting tips

Ash zongzi is strictly a seasonal food. Vendors close up about one week after Dragon Boat Festival; if you visit Taitung outside the festival period you cannot obtain a traditional version.
Ash zongzi should not be refrigerated for more than three days. Eat it quickly after purchase — extended storage causes the texture to harden and the flavor to drop off sharply.
