Journey to 17th-century Java, where soybeans met fermentation and gave birth to one of Indonesia’s greatest culinary inventions — tempeh.
The story of tempeh truly begins when foreign beans met local wisdom.
A Stranger in a Familiar Land
At first, soybeans were outsiders. The Javanese already had plenty of legumes — koro benguk (velvet beans), kacang tolo (cowpeas), and kacang hijau (mung beans). These were familiar, woven into the rhythm of traditional cooking. Soybeans, on the other hand, were tougher, bland, and somewhat resistant to local tastes.
But the Javanese people had a gift for adaptation. They never treated new things as threats; they transformed them. The arrival of soybeans sparked curiosity in home kitchens. Women soaking the beans noticed that when left wrapped in banana leaves overnight, something magical happened — a delicate white film formed, knitting the beans together into a soft, fragrant cake.
They didn’t have microscopes or fermentation charts, yet they knew instinctively that this was good. This was food.

The First Tempeh
Historians cannot pinpoint the exact birthplace of tempeh, but most agree it was somewhere in Central Java, perhaps around Yogyakarta or Surakarta, where traditional fermentation practices thrived.
By the late 1600s, during the Mataram Islamic Kingdom, tempeh had already become known in the region. The Serat Centhini, a 19th-century Javanese literary encyclopedia, immortalized it through the mention of témpé benguk — a fermented dish made from velvet beans. This was evidence that the technique of controlled fermentation predated the use of soybeans.
Over time, soybeans replaced other legumes because they produced a smoother, more cohesive texture and richer flavor. The name tempeh remained, preserving the linguistic thread from témpé benguk to the new soybean version.
And so, the foreign bean found its home in the tropics — reshaped by local hands, renamed in a local tongue, reborn through local culture.
Food for the Common People
Tempeh’s earliest consumers were not kings or merchants but farmers, laborers, and villagers. It was cheap, filling, and nutritious — a perfect companion to rice. In a world where meat was rare and expensive, tempeh became the daily source of protein for the masses.
Its simplicity was its strength. The process required no fancy tools or wealth: just soybeans, banana leaves, and the right climate. Anyone could make it, and everyone could share it.
In a society that valued communal life — gotong royong — tempeh fit perfectly. Families would ferment large batches and exchange portions with neighbors. It became more than food; it was a gesture of goodwill, a daily reminder that sustenance is best when shared.
The Colonial Encounter
When the Dutch arrived and established their colonial rule, they brought with them European attitudes about food — rigid hierarchies of class and taste. To them, meat and dairy symbolized civilization, while plant-based foods were seen as primitive or “native.”
Tempeh was dismissed as voedsel voor de inlander — “food for the natives.” In the colonial imagination, it belonged to the poor and unrefined. Yet, while European settlers ate imported canned goods, Javanese villagers were quietly thriving on a balanced, sustainable diet rich in fermented foods.
The irony, of course, would only become clear centuries later: those “primitive” foods were far healthier and more ecologically sound than the meat-heavy diets of the colonizers.
The Science Behind the Mystery
For hundreds of years, the magic of tempeh was purely experiential. Nobody knew why it worked — only that it did. It wasn’t until the early 20th century that scientists, many of them Dutch, began studying it seriously.
They identified the mold responsible: Rhizopus oligosporus. This friendly fungus not only held the beans together but also broke down complex proteins and fats into simpler, more digestible forms. It enriched the soybeans with vitamins, particularly B12 — something previously thought to exist only in animal products.
In short, the humble village food turned out to be a scientific marvel. Nature had crafted, through the hands of rural Indonesians, one of the most nutritionally complete plant-based foods on Earth.
Tempeh as a Mirror of Javanese Values
Even the wrapping — banana leaves or waru leaves — has meaning. The leaf breathes, letting air flow and life form inside, while imparting a subtle aroma. Nothing is wasted. Nothing is rushed. The result is not only nourishment for the body but a quiet lesson for the spirit.
The Everyday Art of Eating Tempeh
In villages across Java, tempeh found endless expression. It was sliced thin and deep-fried into tempe goreng — crisp, golden, and irresistible. It was marinated in sweet soy sauce and coconut sugar to make tempe bacem, a beloved comfort dish. It was mixed into soups, stews, and sambal, or dried into crackers for long journeys.
Tempeh became the great equalizer. Whether eaten by farmers in the fields or by families in city homes, it connected everyone through a shared flavor of home. Its taste — nutty, slightly earthy, and deeply satisfying — became synonymous with the word “simple happiness.”
From Humble Kitchens to Cultural Identity
By the late 19th century, tempeh had become inseparable from Javanese identity. Travelers and scholars noted its ubiquity, describing how it appeared at nearly every meal. Despite colonial prejudice, tempeh endured. It survived not because it was fashionable, but because it was essential — an everyday food that required no permission to exist.
For centuries, it remained unbranded, unadvertised, and uncelebrated outside Java. Yet within the island, it was a quiet symbol of resilience: proof that the Javanese could feed themselves with ingenuity rather than wealth.
The Philosophy of Adaptation
If there’s one thing the story of tempeh teaches, it’s adaptation. Foreign beans became local cuisine. Accidental fermentation became deliberate craft. A poor man’s food became national pride.
Tempeh’s evolution reflects the adaptability of Indonesia itself — a nation built from countless islands, cultures, and ideas that blend into something wholly unique. Tempeh is Indonesia in miniature: diverse ingredients bound together by warmth, patience, and cooperation.
A Legacy That Grew Beyond Borders
What began as a local discovery would, centuries later, become a global movement. Today, tempeh appears in vegan cafés in Amsterdam, health stores in California, and Michelin-star menus in Tokyo. Yet, its soul remains Javanese — rooted in that same gentle partnership between human hands and microscopic life.
The world now celebrates tempeh for its nutrition, sustainability, and flavor. But in Java, it remains what it has always been: makanan rakyat — the people’s food.
A Call to Taste History
Tempeh’s birth wasn’t an accident. It was an act of quiet genius — the perfect meeting between nature and necessity, simplicity and wisdom. To eat tempeh is to taste that history, to honor the generations who nurtured a living culture long before science caught up.
If you ever visit Indonesia, don’t just eat tempeh — experience it. Visit the small villages where it’s still wrapped in banana leaves, smell the earthy warmth as it ferments, and taste the difference between what’s made by machines and what’s made by care. Come to Malang, where tempeh takes on new life as crispy chips and fragrant dishes that keep this ancient tradition deliciously alive.
