Ruisui Mugwort Rice Cakes | Hualien Signature Dish

Mugwort rice cakes (caoziguo) are Taiwan's traditional Qingming grave-sweeping offering — mugwort or cudweed is kneaded into the glutinous rice skin, and after steaming the cakes turn a beguiling green. The Ruisui Township Farmers' Association sets up stalls at weekend markets, and supply increases significantly around Qingming. Both red bean paste and shredded radish-pork fillings are available. In Ruisui's setting of green mountains and white egrets, this moist, herb-fragrant pastry lets travelers taste the most quintessentially Taiwanese seasonal flavor.

What is Ruisui Mugwort Rice Cake

Mugwort rice cakes (caoziguo) are made by extracting juice from mugwort (more common) or cudweed (pai bei cao / Gnaphalium) and mixing it into glutinous rice flour to form the skin, giving the finished product a green hue and a light herbal fragrance. The Ruisui version comes in sweet and savory: the sweet version is filled with red bean or mung bean paste, smooth and rich; the savory version is filled with stir-fried shredded radish and pork, salty and savory with fat. The skin is soft and sticky after steaming, with a leaf (usually shell ginger or banana leaf) placed underneath to prevent sticking. Peeling off the leaf releases its fragrance, an additional sensory pleasure beyond just the taste.

The Ruisui Township Farmers' Association's agricultural specialty product introduction lists caoziguo as a local traditional pastry, and the association market is the primary public sales venue. Qingming Festival (lunar third month, solar March–April) is the peak season for mugwort rice cakes; some small farmers and home workshops produce large quantities during this period for market sale. A small steady supply exists the rest of the year, but options are fewer and items change quickly. Ruisui Township is famous for the honey-aroma black tea from the Wuhe Plateau; travelers can plan a combined visit to a tea house, buying caoziguo and pairing it with a freshly brewed pot of honey-aroma black tea — the most local afternoon tea combination.

How to eat it like a local

🌿

Best quality is around QingmingThe two weeks around the lunar third month Qingming Festival are the peak for caoziguo production and quality: the mugwort is at its most tender and the makers are at their most practiced — the most worthwhile time to visit.

☕

Pair with Ruisui honey-aroma black tea for a perfect matchThe caoziguo's light herbal fragrance pairs beautifully with the honey-aroma black tea from Ruisui's Wuhe Plateau — the tea carries a honeyed sweetness — making this the most locally distinctive flavor combination.

🧆

Try one sweet and one savoryOrdering one red bean sweet version and one shredded radish savory version and tasting both highlights the textural layers of the caoziguo skin through sweet-savory contrast. The savory one is closer to a meal, the sweet one suits afternoon tea.

🛍️

Best eaten the same dayThe skin of caoziguo hardens as it cools; re-steaming partially restores the texture but not to its freshly steamed state. Buy at the farmers' association market and eat the same day — it doesn't keep well.

Mugwort rice cakes are a shared traditional pastry of Minnan and Hakka ethnic groups; the Qingming offering culture is documented in folklore literature, and the Ruisui Farmers' Association market is a credible purchasing channel.

Visitor tips

Around Qingming (lunar third month) is peak season; caoziguo at the farmers' association market may be in limited supply. In autumn and winter supply is smaller — confirm availability in advance.
The Ruisui Farmers' Association market is not open every day; visiting on weekends offers more choices. If it is a weekday, try asking at old shops in Wuhe for walk-in purchases.
When buying, ask whether real mugwort is used (rather than food coloring). Properly made caoziguo skin is a darker, duller green rather than a bright vivid green — an evenly bright green suggests added coloring.
