Andaliman vs Sichuan pepper
The short answer
Relatives, not substitutes. Both are Zanthoxylum husks that tingle and numb rather than burn, which is why andaliman is sometimes sold as "Batak pepper" and compared to Sichuan pepper. Andaliman is fresher, greener and far more citrus-forward — closer to lime zest — and is ground raw into the sambals and fish dishes of North Sumatra; Sichuan pepper is warmer and woodier and is toasted. In an arsik, Sichuan pepper gives the tingle and misses the brightness that defines the dish.
Side by side
| Andaliman | Sichuan pepper | |
|---|---|---|
| Botanical identity | Zanthoxylum acanthopodium DC. | Zanthoxylum bungeanum Maxim., Zanthoxylum simulans Hance |
| Part used | fruit, seed | fruit |
| Origin | The genus ranges across the Himalaya, southern China and mainland Southeast Asia; the culinary tradition, and the harvest that supplies it, belong to the highlands around Lake Toba in North Sumatra. | Temperate and montane East Asia, with China the centre of cultivation and use. |
| Flavour notes | citric, lime-like, numbing, resinous, green | citrus, floral, woody, numbing, bitter |
| Heat | Scoville does not apply | Scoville does not apply |
| Flavour | Sharp citrus and a warm, peppery edge, followed by a tingling numbness on the lips and tongue that builds and lingers. | The flavour is citric, floral and mildly bitter, but the flavour is not the point. Within seconds of chewing a husk the lips and tongue begin to buzz — a genuine tingling numbness, closer to a mild electric current or a limb waking up than to any taste. It builds, plateaus and fades over several minutes. Nothing else in this catalogue does this, and no amount of any other spice reproduces it. |
| Aroma | Intensely citric — lime, lemongrass and citronella — with a green, resinous edge. The citrus is louder than in any other Zanthoxylum in this catalogue. | Intensely citric — grapefruit and lemon peel — over a warm woody, faintly floral base. The citrus character is a family trait shared with the rest of the Rutaceae and is the first thing noticed on opening a fresh packet. |
Can you swap them?
Substitution is directional: the answer is often different in each direction, and both are recorded.
Sichuan pepper with Lemongrass
AcceptableSichuan pepper supplies the same kind of tingle from the same genus; lemongrass and a little grated lime zest restore some of the loud citrus that dried Sichuan husks lack. The result is a recognisable approximation, woodier and less green than fresh andaliman.

Works for
- Arsik and other braises
- Sambal andaliman made with dried spice
Does not work for
- Naniura and other raw preparations, where the fresh citrus is the point
- Anywhere Sichuan pepper’s woody, dried-husk note would stand out
Cuisine: Pulls the dish slightly towards Sichuan; in a turmeric braise the effect is small.
Which should you buy?
Andaliman
Fresh or frozen if you can get it, whole dried if you cannot, and crush it yourself just before use. Ground andaliman loses its citrus almost immediately.
Sichuan pepper
Buy whole husks and buy them small. This is the strongest whole-over-ground recommendation in the catalogue, because what fades is not merely the aroma but the effect: an old jar of ground Sichuan pepper is inert, and the usual conclusion drawn is that the spice is overrated rather than that the jar is dead. Sieve the black seeds out before grinding — they are grit and bitterness and nothing else — and toast the husks for half a minute first. Then test one on your tongue. Nothing else in this cabinet tells you so directly whether you have wasted your money.
