Jimbu
Also known as jimbu leaves, Himalayan dried onion leaf
Quick answer
The dried leaf of a wild Himalayan onion, gathered in the high valleys of Nepal and fried in ghee to season dal. It tastes of something between chive and shallot with a hay-like depth, and in Thakali cooking it is as expected in the lentils as salt.

Other names
What this spice is called elsewhere, and where the translation is not clean.
jimbuजिम्बु
Nepali
The name covers more than one wild Allium species gathered in the high Himalaya. It does not mean garlic chives or ordinary chives, though both are sometimes offered in its place abroad.
Flavour and aroma
Savoury and allium-sweet, gentler than garlic and deeper than chive. Its effect in a dal is closer to that of a good stock than to that of a raw onion.
Dried, the smell is mild and hay-like. Fried in ghee it opens into something between chive, shallot and garlic, with a toasty depth.
Fine brownish-green dried strands, like dry grass.
Wiry dried strands that crisp in hot fat and soften in a dal.
Heat
Pungency scale: none — this spice is not pungent
No heat.

Foods
Lentils
ClassicJimbu exists in the kitchen to finish dal. Fried in ghee and poured over black lentils, it gives the savoury allium depth that makes Thakali dal recognisable, and the dal would be flat without it in exactly the way an Indian dal is flat without its tadka.
How: Thakali black lentil dal; Everyday dal
Add alongside: Cumin, Asafoetida
Potato
StrongPotato curries and simple fried potatoes in Nepal are often tempered with jimbu, whose onion-and-chive savour is a natural partner for potato in the way chives are in European cooking.
How: Aloo tarkari
Other spices and blends
Cumin
GoodThe two are fried together in the ghee that finishes a Nepali dal: cumin supplies the warm earthy note, jimbu the allium one. Both are fat-extracted aromas and both are ready in the same few seconds, which is why they share the tempering.
How: Dal tempering
If you have no jimbu
What to use instead, and — more usefully — where each replacement stops working.
Fresh chives cut small and fried briefly in ghee, with a sliver of garlic, give the allium savour. They lack jimbu’s dried, hay-like depth, and dried chives are worse than fresh, having lost most of their flavour.
| Flavour | Aroma | Colour | Heat |
|---|---|---|---|
| partial | partial | partial | n/a |
Works for
- Finishing a dal
- Tempering potatoes
Does not work for
- Thakali dal, where jimbu is the identifying flavour
- Dried chives as the stand-in — too little flavour survives
Asafoetida
SituationalUse: ~0.1× by volume — A pinch — asafoetida is far more concentrated.
Gives a dal the same sulphurous, savoury bottom note from a small amount fried in fat, and none of jimbu’s gentle onion-and-hay character. It is the Indian kitchen’s answer to the same problem rather than a copy of jimbu.
| Flavour | Aroma | Colour | Heat |
|---|---|---|---|
| partial | different | different | n/a |
Works for
- Everyday dal when no jimbu is available
Does not work for
- Any dish where jimbu is named and expected
- Cooks who dislike asafoetida
Preparation and use
Heat a spoonful of ghee until very hot, add a pinch of jimbu — with cumin, a dried chilli or a grain of asafoetida if you like — and let it sizzle and darken for a few seconds. Pour the fat and leaves over the dal and cover the pot for a minute so the aroma is caught.
Fried in ghee or oil and poured over dal, above all Thakali black lentil dal; also used to temper potatoes, kwati and pickles. It seasons lentils in the way stock seasons a soup, and its absence is noticed more than its presence.
- frying — Fried for a few seconds in hot ghee or oil until it darkens and smells strongly, then poured over dal. This is the use: raw, it tastes of very little.
- blooming — Bloomed with cumin, a pinch of asafoetida or dried chilli as a tempering; the fat carries the allium aroma through the dish.
Storage and freshness
| Form | Good for | Conditions | Fridge |
|---|---|---|---|
| Leaf | 6–12 months (typically 9 months) | Cool, dark, dry and closed. | No |
Fry a pinch in a spoonful of hot oil. Good jimbu smells clearly of onion and chive within seconds; old jimbu smells of dry grass.
- No allium smell when fried
- A musty smell
- Strands gone soft or dark
- Slow loss of aroma
- Moisture uptake leading to mustiness
Quality is not the same as safety
Faded jimbu is a quality matter. Jimbu that has taken up moisture and smells musty or shows mould should be discarded.
Forms
The form the sources describe, and so the one this page is about.
Dried leaf
Wiry dried strands. The only form in ordinary trade.
Crumble a pinch and fry it in hot fat.
Commonly confused with jimbu
Direct comparisons, each with the difference that actually changes what you cook.
Botany
Two high-altitude wild onions are gathered and sold under the one name, and the dried product does not show which it is. Both are accepted species; the attribution of jimbu to them rests on ethnobotanical reporting rather than on any market labelling.
Amaryllidaceae
The onion family, in the current classification that places Allium in Amaryllidaceae rather than in a family of its own.
The slender leaves, dried into wiry, hay-like strands. Not the bulb.
Small, clump-forming wild onions of alpine pastures and dry slopes, with narrow leaves and heads of small purple-pink flowers. The leaves dry to fine brownish-green strands that look more like hay than like a spice.
Commonly confused with
Another Allium leaf, and the obvious stand-in abroad. Fresh chives are milder and greener; dried chives lose most of their flavour. Jimbu is a dried leaf designed to be fried, and its flavour survives drying in a way chives do not.
The same genus. Fried jimbu gives a dal an onion-and-shallot savouriness without the sweetness of cooked bulb onion.
Not related, but the other way South Asian cooks give a dal a sulphurous allium note from a pinch of something fried in fat. Asafoetida is far stronger and more pungent.
How it is grown
The plant, how it is propagated and farmed, what threatens the crop, and where it is produced now. Crop diseases here are plant health, not food safety.
The leaves of two wild onions of the high Himalaya. In Allium przewalskianum, the one with a full botanical description, they are very narrow — 0.5–1.5 mm wide, half-round to round in section and four- or five-angled — and rise from clustered bulbs wrapped in a red, netted tunic, beside a flowering stem 10–40 cm tall. It grows in scrub, on dry slopes and in rock crevices at 2000–4800 m from western China to Nepal, India and Pakistan, and flowers from June to September. Allium hypsistum, recorded under the Nepali name jimbu, is known only from Nepal, from about 5500 m.
Where it comes from and how it is made
The high Himalaya and the Tibetan plateau, where the source species grow wild on alpine pastures and dry slopes.
- Nepal (Mustang, Manang, Dolpa and other high trans-Himalayan districts) — major producer. Gathered from the wild and increasingly grown in kitchen plots at altitude.
- India (Uttarakhand) — notable producer
- China (Tibet) — notable producer
The leaves are cut in summer and dried, and the dried strands are bundled or bagged for sale in lowland markets.
Cold, dry, high-altitude conditions in the rain shadow of the main Himalayan range.
Buying and quality
- Bought from a Nepali grocer, where it is sold in small bags of dried strands.
- Greenish rather than dark brown strands.
- Dry and crisp, not limp.
- A clear onion smell when a pinch is fried.
Culture
Recorded by tradition rather than merged into one narrative — these are genuinely different practices.
Thakali — Thak Khola, Mustang
Among the Thakali of Thak Khola, Mustang, Nepal.
Thakali cooking, from the Kali Gandaki valley and now familiar across Nepal through its restaurants, finishes its black lentil dal with jimbu fried in ghee. The dal-bhat set that Thakali kitchens are known for is recognised partly by this smell.
- Jimbu-tempered black lentil dal
- Thakali dal-bhat
Nepal more widely
Across the hills jimbu tempers dal, potato dishes, kwati (a mixed-bean soup) and pickles. It stands in the same place in a Nepali kitchen that asafoetida does in many Indian ones: a pinch of something fried that makes the lentils taste finished.
- Dal tempering
- Kwati
- Aloo tarkari
What it is called
- Nepali: जिम्बु (jimbu)
- Nepali: झानेको (jhaneko)
