At first glance, enset looks like a banana plant.
It has a thick trunk-like pseudostem, enormous paddle-shaped leaves and the unmistakable tropical appearance of a member of the banana family. A mature plant can tower over the people cultivating it.
Yet the fruit is not what Ethiopian farmers are waiting to eat.
Instead, the important food is hidden inside the massive plant itself.
For generations, communities in the Ethiopian highlands have scraped, grated, squeezed and fermented the starch-rich tissues of Ensete ventricosum, commonly called enset or the false banana, transforming it into several distinctive foods.
The best known is kocho, a fermented staple usually cooked into bread.
Much rarer is bulla.
Bulla is the fine starch recovered from liquid squeezed out during enset processing. Once separated and dried, it becomes a pale starch-rich ingredient that can be stored and later rehydrated to make porridge, dumpling-like foods, pancakes and thick preparations enriched with milk and seasoned butter. Slow Food’s Ark of Taste describes bulla as considerably harder to find today than kocho and says its longer processing contributes to a higher price.
Behind this modest white starch lies one of Africa’s most extraordinary agricultural systems.
Enset feeds or helps feed around 20 million Ethiopians, particularly in southern and southwestern Ethiopia, yet remains almost unknown throughout most of the world.
Bulla may be even less familiar.
It is the rare food hidden inside an already little-known crop.
The Banana That Does Not Give You Bananas
Enset belongs to the banana family, Musaceae, and is closely related to the bananas familiar in supermarkets.
That explains its appearance.
But domesticated Ethiopian enset is cultivated for a completely different reason.
Instead of growing the plant primarily for sweet fruit, farmers harvest the enormous pseudostem and underground corm, both of which contain substantial quantities of carbohydrate. Kew describes enset as a wild African banana relative domesticated in the Ethiopian Highlands and notes that the domesticated crop has become a staple for millions of people.
The pseudostem looks like a trunk but is actually formed by tightly overlapping leaf bases.
The corm sits beneath the plant.
Together they become the raw material for Ethiopia’s characteristic enset foods.
This is why the name false banana is simultaneously helpful and misleading.
It looks like a banana.
It is related to bananas.
But the food system surrounding it has almost nothing to do with peeling and eating a banana fruit.
Three Important Foods from One Plant
Enset is commonly transformed into three principal foods:
Kocho is made from the scraped pseudostem and grated corm, which are processed and fermented before being cooked.
Bulla is the fine starch recovered from liquid expressed during processing.
Amicho is made by cooking pieces of the corm more directly, rather like a root or tuber vegetable. Scientific literature consistently identifies kocho, bulla and amicho as the three major food products derived from enset.
The distinction helps explain why bulla is unusual.
Kocho retains much more of the fibrous plant material.
Bulla is the refined portion.
During processing, liquid containing suspended starch is separated from the scraped plant material. The starch settles or concentrates and can then be collected as bulla. Slow Food describes the finished product as a white starch or powder capable of being stored for long periods.
In modern terms, it is almost like producing a specialty starch from a giant banana relative.
But “almost” matters.
Bulla is not simply industrial starch.
Its production is tied to household knowledge, specific enset varieties, regional food traditions and a labor-intensive processing system.
How Bulla Emerges from the Plant
Processing an enset plant is substantial work.
The plant must first reach an appropriate stage of development. The useful portions are then separated and processed, traditionally through methods involving scraping the pseudostem and reducing the corm.
As this plant material is worked and squeezed, a starchy liquid can be separated.
Bulla comes from that liquid fraction.
Slow Food describes the process as squeezing the enset scrapings and pulp, separating off the liquid and allowing the starch within that liquid to concentrate into the product known as bulla.
Scientific descriptions similarly distinguish bulla from kocho by describing bulla as being produced from dehydrated starch-rich juice or exudate, while kocho comes from the solid scraped and grated plant material.
The exact traditional procedures vary among communities, and enset processing should not be imagined as one standardized factory method.
It is a body of regional knowledge.
Women Hold Much of the Processing Knowledge
One of the most important parts of the enset story is often missing from descriptions of the crop.
The processing has traditionally depended heavily upon women.
Research on enset starch notes that traditional processing work is performed primarily by women, while ethnobotanical studies have documented detailed Indigenous knowledge surrounding enset varieties, harvesting and food preparation.
That makes bulla more than the product of a plant.
It is the product of skill.
Someone has to know:
When the enset is ready.
Which parts should be used.
How finely they should be processed.
How the starch-rich liquid should be separated.
How the material should be handled and stored.
And how the finished bulla should later be turned into food.
This knowledge has been developed and passed between generations in communities where enset cultivation is central to household life.
The supermarket version of agriculture often hides this kind of expertise.
Bulla makes it impossible to ignore.
What Does Bulla Look Like?
Finished bulla is far less dramatic than the enormous plant from which it comes.
It may appear as a pale or white starch-rich powder or dough-like material, depending on how it has been processed and stored.
Slow Food describes a complex aroma reminiscent of fresh cheese.
Flavor descriptions can vary greatly because bulla rarely appears on the table completely by itself.
Its role is more comparable to flour, starch or grain.
What surrounds it often determines the final flavor.
Milk can make it creamy.
Seasoned butter adds richness and aroma.
Spices add warmth.
Cooking changes its texture from powdery starch into something smooth, thick or gelatinous.
Its defining quality is therefore not an aggressive flavor.
It is texture and adaptability.
Bulla Porridge
One of the simplest ways to understand bulla is through porridge.
The dried starch is rehydrated and heated until it thickens.
Because bulla is heavily starch-based, the mixture can develop a smooth and substantial consistency.
Slow Food lists porridge among its traditional preparations.
Depending upon the region and household, additional ingredients can transform that base.
Milk increases richness.
Butter contributes fat and flavor.
Spices turn a relatively neutral starch into something deeply aromatic.
The result demonstrates why bulla historically had value.
A small quantity of concentrated starch can become a substantial food once combined with liquid.
Bulla with Milk and Seasoned Butter
One especially interesting regional preparation comes from western Oromia.
Slow Food records bulla powder being mixed with fresh milk and seasoned butter, then cooked until the mixture develops a jelly-like consistency.
That texture may surprise someone expecting something resembling wheat flour.
Bulla is starch-heavy.
When starch granules absorb water and are heated, they swell and thicken the surrounding liquid.
The result can therefore be glossy, cohesive and almost pudding-like.
Seasoned Ethiopian butter adds another layer.
Known in different contexts as niter kibbeh or related regional preparations, spiced clarified butter can contain aromatic ingredients that transform a mild starch into something far more complex.
Explore the cuisine: A selection of Ethiopian spices can introduce readers to some of the distinctive aromas and flavors found throughout Ethiopian cooking.
Bulla provides the body.
The dairy and spices provide much of the personality.
A Couscous-Like Preparation
In southern Ethiopia, bulla can take another form entirely.
Slow Food describes a preparation in which bulla is combined with traditional seasoned butter and spices until it forms small grains resembling couscous.
This is an excellent illustration of the ingredient’s versatility.
The same base product can become:
A porridge.
A thick jelly.
Small grains.
Dumpling-like pieces.
Pancakes.
Or a drink.
Bulla behaves less like one finished food than a raw material from which many foods can be constructed.
Dumplings and Pancakes
Slow Food also documents bulla being rehydrated and used for dumplings and pancakes.
Those preparations make sense because of its starch content.
With appropriate hydration and cooking, starch provides structure and cohesion.
But bulla does not behave exactly like wheat flour because it does not contain wheat’s gluten-forming proteins.
Its texture is consequently its own.
Traditional cooks developed methods adapted to the ingredient rather than expecting it to behave like imported cereal flour.
That distinction is important.
Calling bulla “Ethiopian flour” is convenient shorthand.
Calling it a starch is closer to the culinary truth.
Explore Ethiopian cooking: An Ethiopian cookbook can introduce readers to traditional dishes, ingredients, spices, and cooking techniques from across the country’s cuisine.
Bulla Versus Kocho
To understand why bulla has become rare, it helps to compare it with kocho.
Kocho is the major fermented enset staple.
The scraped pseudostem and grated corm are processed into a fibrous, starch-rich mass that undergoes fermentation before being prepared as food. Research identifies kocho as one of the principal foods sustaining enset-growing households.
Bulla represents a more refined fraction of that same processing system.
The difference is somewhat analogous to processing a grain into a general meal and then separating a more refined component—but the analogy is imperfect because enset processing is botanically and technologically distinct.
The practical consequence is straightforward:
Producing bulla requires additional work for a smaller amount of highly refined food.
That helps make it less common.
Slow Food reports that bulla is now much rarer than kocho, with its longer processing time helping explain its higher market price.
Why Is Bulla Becoming Rare?
Rarity can have several causes.
Sometimes a plant itself becomes endangered.
That is not quite what is happening here.
Enset remains extremely important in Ethiopia and continues feeding millions of people.
The rarity concerns bulla as a particular processed food.
Slow Food reports that bulla can be difficult to find in markets even where kocho remains common. It also notes a social problem: some people have come to regard bulla as an old-fashioned food associated with poverty.
That kind of stigma can be devastating to traditional foods.
A food does not have to disappear because nobody can make it.
It can disappear because younger consumers no longer want to be associated with it.
As incomes and diets change, packaged foods, wheat products, rice and other commercially convenient ingredients can displace labor-intensive traditional foods.
Once demand falls, the knowledge required to produce them can begin disappearing as well.
When “Poor People’s Food” Becomes a Treasure
Food history is full of reversals.
Lobster was once considered humble food in parts of North America.
Polenta was associated with peasant diets.
Many traditional whole grains fell from favor before being rediscovered as premium products.
Bulla may contain a similar contradiction.
Its reputation as an old or poverty-associated food can cause it to disappear precisely as chefs, agricultural researchers and food historians begin recognizing how unusual it is.
The irony is striking.
A food based on an Indigenous crop capable of helping millions of people withstand difficult growing conditions could be rejected because it seems insufficiently modern.
Slow Food’s inclusion of bulla in the Ark of Taste is intended to draw attention to precisely this kind of threatened food heritage.
Enset: The “Tree Against Hunger”
Bulla’s story becomes much larger when viewed through the crop that produces it.
Enset has earned the nickname “tree against hunger.”
Kew scientists describe it as a staple for around 20 million Ethiopians and emphasize its extraordinary importance to household food security.
One reason is that enset does not have to be harvested on one narrow annual schedule like many cereal crops.
Farmers can maintain plants of different ages and harvest them according to household needs.
This flexibility effectively allows living plants to function as food reserves in the field.
Research also identifies drought resilience, high biomass production and flexible harvesting as major reasons enset-based systems help households cope with food shortages.
For families living with uncertain rainfall, that flexibility can be enormously valuable.
An Agricultural Bank Account
Imagine a crop that does not require every plant to be harvested at the same moment.
Instead, some plants remain growing while others are selected according to need.
That is one of enset agriculture’s great advantages.
The household effectively stores carbohydrate in living plants.
If another harvest performs poorly, enset can provide a buffer.
If drought creates food pressure, more plants can be harvested.
Research from Kew and collaborators found that Ethiopian farmers increased enset cultivation following severe drought, supporting the idea that the crop functions as a climate-coping strategy.
Bulla represents the most refined portion of that stored carbohydrate.
It is almost a reserve extracted from a reserve.
A Crop Domesticated in Ethiopia
Wild relatives of enset occur across a much broader area of Africa.
But domesticated enset agriculture is uniquely associated with Ethiopia.
Kew notes that wild enset occurs from Ethiopia southward through parts of Africa, while the plant was domesticated as a food crop in the Ethiopian Highlands.
That makes enset an extraordinary example of agricultural innovation.
Communities took a banana relative whose fruit offered little food value and built an entire agricultural system around other portions of the plant.
The transformation required generations of experimentation.
Which varieties were suitable?
When should they be harvested?
How should the tissues be processed?
How should fermentation be controlled?
Which products stored best?
Bulla is one answer to those questions.
Hundreds of Enset Types
Enset is not a single uniform crop.
Ethiopian farmers maintain numerous named landraces selected for qualities such as yield, maturation, food characteristics, disease tolerance and local environmental adaptation.
Research into enset genetics and agricultural diversity emphasizes the importance of this farmer-maintained variation.
Different landraces may also be preferred for different foods.
A plant valued for kocho may not necessarily be identical to one considered particularly suitable for bulla or amicho.
That diversity matters for food security.
If every household grew genetically identical plants, one disease or environmental stress could become far more destructive.
Traditional crop diversity provides options.
More Than Food
Enset is remarkable because almost every part of the plant can serve some purpose.
Research describes enset as a multipurpose crop, contributing not just food but livestock feed, fiber, household materials and environmental services within Ethiopian farming systems.
The enormous leaves may be useful around the household.
Fibers extracted during processing can become rope or other materials.
Plant residues can feed animals or return organic material to the farm.
Enset also commonly grows within diverse home-garden systems alongside coffee, fruit trees, vegetables, spices and livestock.
The crop therefore occupies a role far larger than the calorie value of bulla or kocho.
It helps structure an entire farming landscape.
Why Has the Rest of the World Barely Heard of It?
This may be the most surprising question.
How can a crop feeding around 20 million people remain virtually unknown elsewhere?
Part of the answer is geography.
Domesticated enset production remains heavily concentrated in Ethiopia.
Part is processing.
Unlike potatoes or bananas, enset is not a simple harvest-and-eat crop. Traditional processing requires substantial knowledge and labor.
Part is research.
Kew describes enset as globally underrecognized despite its importance and has investigated whether suitable future climates might allow cultivation across a much wider region.
And then there is familiarity.
Global agriculture is dominated by a relatively small number of crops.
Wheat.
Rice.
Maize.
Potatoes.
Soybeans.
Foods outside that global commodity system can feed millions and still remain largely invisible internationally.
Bulla sits at the extreme edge of that invisibility.
Could Enset Become More Important in a Changing Climate?
Scientists are increasingly interested in enset precisely because agriculture faces a changing climate.
The plant is perennial, relatively drought tolerant and flexible in harvest timing.
Kew research has described it as an important climate-resilient food-security crop and investigated its potential beyond its current Ethiopian cultivation zone.
This does not mean enset should simply be exported around the world as the next fashionable “super crop.”
Agricultural success depends on culture as well as climate.
Ethiopian farmers possess generations of knowledge about propagation, varietal selection, processing and food preparation.
The plant cannot be separated from that knowledge and expected automatically to perform the same role elsewhere.
Any wider interest should recognize the Ethiopian communities responsible for developing and maintaining the crop.
Bulla Is Mostly Starch
From a nutritional standpoint, bulla’s defining feature is carbohydrate.
Recent food-science research describes bulla as a highly starch-rich enset product, with its refined nature giving it less fiber than less processed enset foods.
That means bulla should not be imagined as a nutritionally complete food on its own.
Traditional combinations make sense.
Milk contributes protein and fat.
Seasoned butter contributes fat and energy.
Other dishes eaten alongside enset foods can provide protein, vegetables and micronutrients.
This is typical of staple foods.
Rice does not need to contain everything.
Neither does wheat bread.
Bulla’s role is largely to supply energy and texture within a broader diet.
The Value of a Food That Can Wait
One of bulla’s most important qualities may be less glamorous than flavor.
It can be stored.
Slow Food reports that properly prepared bulla powder can remain usable for years.
For a household living without the storage systems available in industrial agriculture, a concentrated dry food has enormous value.
Fresh foods spoil.
Milk sours.
Vegetables wilt.
But dried starch waits.
When needed, water turns it into food again.
That simple cycle—
extract, dry, store, rehydrate
—is one of humanity’s oldest food-security technologies.
Bulla represents an Ethiopian version developed from a crop unlike nearly anything found in a Western pantry.
Nearly Forgotten, but Not Gone
Calling bulla “nearly forgotten” does not mean nobody eats it anymore.
It remains part of living Ethiopian food traditions.
But compared with kocho, its visibility has declined. Slow Food describes it as rare in markets and significantly less common than the better-known fermented enset staple.
That creates an important distinction.
A food can survive in households while disappearing commercially.
It can remain known to elders while becoming unfamiliar to younger people.
It can continue being produced in one region while becoming virtually invisible elsewhere.
Traditional foods rarely vanish all at once.
They fade.
That is why documenting them while knowledge remains active matters.
The Rare Food Hidden Inside the False Banana
Bulla begins with an enormous plant that looks as if it should produce bunches of familiar bananas.
It does not.
Instead, Ethiopian farmers harvest carbohydrate hidden inside its pseudostem and corm.
They scrape the plant.
Process the pulp.
Separate the starch-rich liquid.
Recover the fine starch.
Dry it.
Store it.
And later transform it again into porridge, dumpling-like foods, pancakes or creamy preparations enriched with milk and butter.
Every step moves farther from what someone unfamiliar with enset would expect from a banana relative.
That is what makes bulla such an extraordinary food.
It is not exotic because someone recently invented a clever new starch.
It is rare because an ancient Ethiopian agricultural system learned to find nourishment in a part of a plant most of the world never thought to eat.
Today, as scientists study enset for its potential contribution to climate resilience and food security, the humble starch separated during its processing deserves attention as well.
Bulla is pale, quiet and easily overlooked.
But behind it stand millions of people, generations of agricultural knowledge and one of the world’s most remarkable food crops.
The false banana does not give Ethiopia bananas.
It gives something arguably more valuable:
food that can wait until it is needed.
