Ma-wai Soup: From the Jute Fields of Nantun to a Summer Bowl of Bitter-Sweet Green Broth on Taichung's Table

At a Glance
Ma-wai is the tender shoot of the jute plant. During the Japanese colonial period, the Taiwan Governor-General promoted large-scale jute cultivation in the Nantun area of Taichung to supply the gunny sack industry. Local farmers picked the young leaves on the side, rubbed off the mucilage and bitter juice, then simmered them with sweet potato and dried small fish into a thick green broth—a home-style summer dish to clear heat and soothe the liver¹². When plastic bags became widespread in the 1960s, jute fields virtually vanished within three decades, but ma-wai soup did not disappear with them. It went from being an industrial by-product to a flavor code by which Taichung people recognize one another—cross south of Changhua or north of Fengyuan and almost no one has tasted it³⁴. Today, the Ma-wai Culture Museum on Wanhe Road in Nantun is the 32nd community culture museum in Taiwan and the first privately run one in Taichung, sponsored by the Council for Cultural Affairs—and the only museum on the island dedicated to a single local vegetable⁵⁶.

A Green Forgotten by Industry, Remembered by the Tongue

The first time ma-wai soup is set on the table, it looks like a bowl of spinach puree that wandered into the wrong restaurant. Deep green, thick, dried little fish floating on the surface, chunks of sweet potato settled at the bottom. The first three seconds on the tongue are the bitterness of fresh grass; by the fifth second the sweetness of the sweet potato rises, and a lingering sweetness coats the throat—this is the summer Taichung people have drunk since childhood⁴⁷.

But the star of this bowl was never meant to be drunk.

Jute is an annual herb in the family Tiliaceae. Two species are commonly found in Taiwan: round-fruited jute (Corchorus capsularis) and long-fruited jute (Corchorus olitorius). The former has stronger fibers and is the main material for rope-making and sack-weaving; the latter has thicker leaves rich in mucilage—the version known in the Arab world as "molokhiya" (the king's vegetable) and used in soups. Taichung's ma-wai soup primarily uses long-fruited jute⁸⁹. According to historical records, jute was first transplanted to Xikou, Chiayi, from Fujian during the Kangxi era. In the Japanese colonial period, the Governor-General's office promoted large-scale cultivation in the Taichung Basin to meet the surging demand for gunny sacks to package rice for export. Nantun (formerly Litoudian), with its well-drained red soil, became a major producing area⁵¹⁰¹¹.

💡 Did You Know?
The entire economic value of the jute plant lies in the fiber of its stem. The leaves were originally waste that farmers discarded at the edge of the field. Ma-wai soup was born because farmers could not bear to waste them—rub the young leaves, wash out the bitter juice, toss them into the pot, and it turned out to be a perfect summer heat-reliever²¹⁰.

Why Only Taichung? Three Geographic Lines

The distribution of ma-wai soup is almost a map of old jute fields. The Taichung City Government's food-and-agriculture teaching materials put it plainly: "Cultivation is rare south of Changhua and north of Fengyuan"². This north-south strip of roughly 40 kilometers corresponds precisely to the densest jute contract-farming zone during the Japanese era—especially along the Wanyuanxi (Hemp-Garden-Head Stream) in Nantun, once the area with the largest farmland and the highest ma-wai output in all of Taichung, locally called "the new homeland of ma-wai"¹².

Even more critical is the processing threshold. Ma-wai leaves are rich in mucilage and bitter compounds and must be "rubbed to remove the juice." Rub too little and the whole bowl is unpalatably bitter; rub too much and the leaves fall apart and lose their texture. Old Nantun residents have a saying: "Rub the ma-wai until it foams, but don't rub until the fibers snap"¹⁴. This is a dish with no SOP, only hand-feel—every household made it every day back then, so there was never a chance for outsiders to learn it.

From Bali-pen to Wanhe Temple: A Fiber's History of Taiwan

To understand why ma-wai is in Taichung, you first have to understand why Taiwan grew jute.

1. 1895 — Japan takes over Taiwan and launches a rice-export-to-Japan program, causing demand for gunny sacks to surge¹⁰¹³
2. 1910s–1940s — The Taichung Basin becomes the largest jute-producing region in Taiwan; Nantun, Wuri, and Dali all have ma-liao (bark-stripping workshops)⁵¹¹
3. 1960s — PE plastic bags enter Taiwan's packaging industry; gunny sacks lose cost competitiveness³
4. 1970s — Jute cultivation area collapses by 90 percent within a decade; most ma-liao are demolished¹⁰
5. 1997 — Wanhe Temple establishes the Wanhe Cultural and Educational Foundation, launching a Nantun local-culture preservation project⁶
6. 2003 — With sponsorship from the Council for Cultural Affairs, the Wanhe Cultural and Educational Foundation opens the Ma-wai Culture Museum on the fifth floor of the Wanhe Cultural Building—the 32nd community culture museum in Taiwan and the first privately run one in Taichung⁵⁶¹⁴

📝 Curator's Note
Taiwan has many lost economic crops—camphor in Miaoli, sugarcane in Yilan, sisal in Pingtung—and after they exited the stage, most industrial sites became museums or cultural-creative parks. But only ma-wai survived in the most everyday form there is: a dish. A bowl of soup preserves a chapter of history better than a factory ever could.

The Politics of Bitterness

Why don't people in Taipei drink it? Why not Tainan? Beyond the fact that it isn't grown there, there is a more subjective reason: bitterness.

People outside central Taiwan generally have a lower tolerance for bitterness. Tainan leans sweet, Taipei leans salty, Hakka cuisine leans salty-umami—only Taichung developed a "slightly bitter, then sweet" flavor line. Daamian-geng (alkaline-water noodles with a faint bitter edge) and ma-wai soup are the two pillars of that line¹. Scholar Wang Pai-ren wrote in the Cultural Taichung quarterly: "For Nantun people, the phrase kujin ganku (bitterness ends, sweetness comes) is something they truly eat with their mouths."¹

This is also why ma-wai soup has been hard to "unify north and south." It isn't that it doesn't taste good—its deliciousness requires a whole set of local palate training. You have to accept the bitterness of the first sip to earn the sweetness of the third.

A Bowl of Soup's Nutrition and Medicinal Properties

Setting the industrial history aside, from a nutritional standpoint ma-wai is an impressive report card. Every 100 grams of ma-wai is rich in beta-carotene, lutein, vitamin A, phenolic compounds, dietary fiber, and minerals including potassium, calcium, and iron—a low-calorie, high-antioxidant green leafy vegetable⁷. Traditional Chinese medicine texts classify jute leaves as cold-natured and bitter-tasting, recording effects of "regulating qi to relieve pain, draining pus and detoxifying," indicated for hemoptysis and hematemesis⁹—which maps precisely onto the folk experience of Nantun elders who say "drinking ma-wai soup in summer clears the liver and reduces internal heat"²¹⁵.

Long-fruited jute is also promoted in agricultural extension materials as a "natural thickening ingredient" because its leaves contain natural mucopolysaccharides that can make soups thick and smooth without cornstarch—the scientific reason ma-wai soup achieves its distinctive thick, green texture⁸.

From the Family Table to the Tourist Stall

At the 2018 Taichung World Flora Exposition, the "Satoyama Living Area" specially planted a new plot of jute, showcasing ma-wai as a representative central-Taichung wild vegetable¹⁶. At the Second Market's old-style rice stalls, on Nantun Old Street with ma-wai ice, and beside the museum with ma-wai cookies and ma-wai vermicelli—in recent years ma-wai has shifted from a home-cooking dish to a tourism symbol⁴⁵¹³.

But older Taichung residents are a little wary. Swap the sweet potato for sago, replace the dried fish with tofu, and some vendors have even launched a "ma-wai matcha latte"—when the "bitterness" in the traditional recipe is layered over with sugar after sugar, is what remains still ma-wai soup? The debate over "whether to season for tourists" has no resolution yet³⁴¹⁵.

⚠️ A Note on Naming
Since the Ma-wai Culture Museum opened in 2003, Nantun cultural-history workers have continuously advocated replacing the common spelling "麻薏" (ma-yi) with "麻芛" (ma-wai), arguing that the character 芛 better matches the ancient meaning "the tender sprout of a plant"—a character that local museum researchers effectively revived and re-invented⁴⁶. But "麻薏" has long been entrenched in everyday Taichung speech, and even city government documents use both characters side by side⁵¹⁷. One ingredient, two spellings, two written forms—this is itself proof of its ambiguous identity.

What a Bowl of Green Soup Can Tell You

Ma-wai soup is not photogenic, does not look good on camera, and unlike pineapple cakes cannot be boxed into a gift set and shipped overseas. It is a green, murky bowl of soup available only in summer and hard to find beyond the Dadu River.

But it remembers something: there was once an island that grew jute, stripped jute, and wove sacks to ship rice back to the Japanese home islands. When that supply chain broke and the fields were replanted with other crops, what was left behind was not a factory or a statue—it was the handful of tender leaves that a farmer's mother could not bear to throw away.

Next time you are in Taichung, find a rice stall and order a bowl of ma-wai soup. Don't rush to finish it—wait for that sweetness to rise from the back of your throat. It is the sound of an industry that sank, and a flavor that stayed.
