Jakhiya
Also known as jakhya, Asian spider flower seed, wild mustard (jakhiya), Cleome viscosa
Quick answer
The tiny seed of a roadside weed that the cooking of Uttarakhand turned into its signature tempering. Fried in mustard oil it crackles like mustard seed and turns crunchy and nutty, and potatoes tossed in it — jakhiya aloo — are the region’s best-known dish of the kind.

Other names
What this spice is called elsewhere, and where the translation is not clean.
jakhiya
Garhwali and Kumaoni — Uttarakhand
Sometimes called wild mustard in English, which it is not: mustard is Brassica, and this is a Cleome, in a different family.
hulhul
Hindi
The plant’s general Hindi name as a weed. In the kitchen, jakhiya is the name that identifies the seed as a seasoning.
Flavour and aroma
Nutty and crunchy, gently bitter, without the pungency of mustard seed.
Faint when raw; fried, toasty and nutty with a slight mustard-like edge.
Tiny dark reddish-brown seeds, darkening when fried.
Crisp and crunchy after frying — part of its appeal on potatoes and greens.
Heat
Pungency scale: none — this spice is not pungent
No heat.

Foods
Potato
ClassicJakhiya aloo — boiled potatoes tossed in mustard oil crackling with jakhiya and dried chilli — is the best-known Uttarakhandi dish built on the seed. The crunchy, nutty seeds give plain potato texture and a toasted flavour.
How: Jakhiya aloo
Add alongside: Asafoetida, Turmeric
Spinach
StrongGreens in the Uttarakhand hills are commonly tempered with jakhiya; its toasty crunch contrasts with soft wilted leaves.
How: Tempered greens
Pumpkin
GoodPumpkin cooked in the hill style begins with a jakhiya tempering in mustard oil, which offsets the pumpkin’s sweetness with a nutty, faintly bitter note.
If you have no jakhiya
What to use instead, and — more usefully — where each replacement stops working.
Mustard seed
AcceptableUse: ~0.75× by volume — A little less, because mustard seed is pungent where jakhiya is not.
Crackles in hot oil the same way and gives a similar popping texture, with a sharper, more pungent flavour and less of jakhiya’s nuttiness.
| Flavour | Aroma | Colour | Heat |
|---|---|---|---|
| partial | partial | close | more |
Works for
- Jakhiya aloo
- Tempering greens
Does not work for
- Reproducing the Uttarakhandi flavour exactly — mustard seed is the obvious substitute and a noticeably different taste
Cumin
SituationalCumin seed fried in oil gives a toasted tempering of the right kind and weight, with its own unmistakable earthy aroma rather than jakhiya’s nutty one. The dish becomes a North Indian jeera aloo.
| Flavour | Aroma | Colour | Heat |
|---|---|---|---|
| different | different | close | n/a |
Works for
- Potato and greens tempering when nothing closer is available
Does not work for
- Any dish meant to taste of the Uttarakhand hills
Cuisine: Turns the dish into the plains version of itself.
Preparation and use
Heat mustard oil until it smokes, then let it cool a moment. Add half a teaspoon of jakhiya with a dried red chilli and let it crackle for a few seconds, add a pinch of asafoetida, then the boiled, cubed potatoes or greens. Keep the heat high enough that the seeds stay crisp.
A tempering seed in the cooking of Uttarakhand: fried in mustard oil for potatoes, greens, pumpkin, radish and dal. It is used where mustard seed or cumin would be used elsewhere in North India, and for crunch as much as for flavour.
- frying — Dropped into very hot mustard oil, where it crackles and pops within seconds and turns crunchy. This is the only way it is used; raw it tastes of little.
- blooming — Used as the first tempering, before dried chilli and asafoetida, for potatoes, greens and dal.
Storage and freshness
| Form | Good for | Conditions | Fridge |
|---|---|---|---|
| Seed | 12–24 months (typically 18 months) | Cool, dark, dry and closed. | No |
Fry a pinch in hot oil: fresh seed pops lively and smells toasty; old seed smells stale or sharp.
- A stale or rancid smell when fried
- Webbing or insect holes
- Slow rancidity of the seed oil
- Insect damage in a seed kept long in an open bag
Quality is not the same as safety
Stale jakhiya is a quality matter. Seed showing insect damage should be discarded.

Botany
Also published as Arivela viscosa, a name some regional floras accept; Kew treats it as a synonym.
Cleomaceae
The spider-flower family, closely related to the cabbage and mustard family but distinct from it.
The small seeds from the long, sticky pods.
A sticky, strong-smelling annual herb with yellow four-petalled flowers and long slender pods, common as a weed of fields and roadsides throughout the tropics and warm temperate regions of the Old World. The seeds are tiny, dark reddish-brown and finely ridged.
Commonly confused with
The nearest in behaviour — both crackle in hot oil and both are used as a first tempering — and the name "wild mustard" invites the confusion. Mustard is Brassica, pungent and round; jakhiya is smaller, ridged and nutty rather than sharp.
Another tiny dark seed used whole in North Indian tempering. Nigella is black, angular and oniony; jakhiya is reddish-brown and toasty.
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 tiny dark reddish-brown seeds from the long slender pods of a sticky annual that is a common weed of fields and roadsides.
How it is propagated
- Seed.
From seed. The seeds have no dormancy and germinate readily once shed; plants begin to flower three to four weeks after germination, and the whole life cycle takes about three months.
Growing conditions
- Altitude · 0–1000 m
Found from sea level up to 1,000 m, under seasonally dry and under humid conditions alike. The handbook describes the plant in tropical Africa; the hill districts of India where the seed is a condiment are not covered by this range.
- Soil
A weed of fallow land, fields, roadsides and wasteland, also found in woodland and grassland. It is often on sandy soils and sometimes on calcareous and rocky ones.
How it is farmed
- Wild harvest · Tropical Africa and India
Mostly gathered. In Africa the leaves are collected from the wild. In India, the handbook says, the plant is rarely cultivated but is gaining in popularity as a low-cost substitute for cumin, and its cultivation is promoted for degraded or marginal land, where it grows with less difficulty than traditional crops.
Most spices are grown in more than one way; none of these is the only one.
In pure stands of 35,000 plants per hectare, seed yields of 600 kg per hectare have been obtained; the handbook does not say where. It adds that the crop is not attacked by insect pests or damaged by wildlife, because the plant is sticky and smells strongly, that it is treated as a noxious weed in some regions, and that it is a host of papaya ringspot virus and of two root-knot nematodes. The account dates from 2004.
Where it comes from and how it is made
A widespread weed of the Old World tropics; its original range cannot be separated from its spread with agriculture.
- India (Garhwal and Kumaon, Uttarakhand) — major producer. Gathered from wild and field-margin plants, and sown in some hill fields, for local use.
A warm-season annual of disturbed ground, tolerant of poor soils.
Buying and quality
- Bought from a supplier of Uttarakhandi produce, or brought down from the hills.
- Clean seed with little chaff or pod debris.
- Lively crackling and a toasty smell when a pinch is fried.
Culture
Recorded by tradition rather than merged into one narrative — these are genuinely different practices.

Jakhiya is the tempering that people from the Uttarakhand hills name when asked what makes their food different: potatoes tossed in jakhiya-crackled mustard oil (jakhiya aloo), greens, pumpkin and dal all begin with it. A weed seed that costs nothing, it stands for the resourcefulness of a mountain kitchen and has become a marker of regional identity as that cooking reaches the cities.
