A dry, galangal-forward Lanna chili dip pounded from grilled dried chili, garlic, shallot, and a heavy hand of fresh galangal, seasoned with salt and a little shrimp paste — no liquid, no simmering. It is paired above all with steamed or boiled mushrooms (hed thop, the seasonal forest mushrooms of the North), but also with steamed or grilled beef and offal, eaten with sticky rice. The galangal is the whole point: most Thai chili dips lean on lime or fish sauce for their character, while nam prik kha leads with the sharp, piney, almost medicinal heat of pounded fresh galangal.
Nam prik kha is an old Lanna home dip from the upland North (Chiang Mai, Chiang Rai, Nan, Mae Hong Son), with no fixed date — like most everyday nam prik it was never written down, only pounded. Its identity is tied to the foraged mushroom season: in the rains, Northern households boil or steam wild forest mushrooms and dip them in this galangal paste, and the dish is documented across Lanna and Tai Yai (Shan) communities on both sides of the Thai-Myanmar border. The name simply combines nam prik (chili dip, literally 「chili water」) with kha, the Thai word for galangal; unusually for a nam prik, galangal is the defining ingredient rather than a background aromatic.
Drier and coarser than most nam prik — closer to a crumbly paste than a relish, with no pooled liquid. It looks dull brick-red flecked with pale gold from the galangal. The first hit is galangal: sharp, resinous, citrus-pine, almost soapy-medicinal in the way ginger never is, riding on top of the smoky dried-chili heat. Underneath sit roasted garlic and shallot sweetness and the low salty funk of shrimp paste. With a plain boiled mushroom it is a revelation — the bland, springy mushroom is a blank canvas the galangal paint goes straight onto. If you can't taste the galangal jumping out, too little went in.
This is a dry-pounded dip, so the mortar order and moisture control are everything. The dried chilies are toasted or grilled until brittle and smoky, then pounded with salt first so they shatter into flakes rather than skidding around the mortar. Garlic and shallot — also grilled — go in next for a roasted sweetness, and the fresh galangal last, pounded just enough to bruise and release its volatile oils without turning to fiber-mush; over-pounding the galangal makes it stringy and bitter. Shrimp paste is dry-roasted before it joins, which burns off the raw ammoniac edge. Because nothing is simmered, the dip keeps the bright top-note of raw galangal — the moment you add liquid or cook it, that piney lift collapses into something flatter and gingerier.
Variations
The classic pairing is with steamed or boiled wild mushrooms; versions for grilled beef, beef offal, or boiled vegetables are common. Some Chiang Rai and Nan households work in a little pla ra (fermented fish) instead of shrimp paste for a deeper funk; Tai Yai (Shan) cooks may pound in roasted dried fish. A few add a squeeze of lime at the table, though purists keep it dry and galangal-clean. Drier, crumblier renditions store for several days; wetter ones are eaten the same day.

8 steps · 20 min active + 5 min waiting
- 14 min
Toast or grill the dried red chilies over a flame until brittle and smoky, then tear off the stems.
- 25 min
Grill the unpeeled garlic and shallots until soft and blackened in patches, then peel.
- 33 min
Dry-roast the shrimp paste in a dry pan or wrapped in foil until fragrant.
- 42 min
Pound the toasted chilies with the salt first until broken into coarse flakes.
Watch outPound the toasted chilies with the salt first — the salt gives them grit to shatter against so they break into flakes instead of skidding round the mortar.
- 52 min
Add the grilled garlic and shallot and pound to a rough paste.
- 63 min
Add the fresh galangal and pound just until bruised and aromatic, keeping it slightly fibrous — do not reduce to mush.
Watch outPound the galangal just until it bruises and smells aromatic — keep it slightly fibrous; grind it to mush and it turns stringy and bitter.
- 71 min
Work in the roasted shrimp paste and taste for salt; the dip should stay dry and crumbly.
Watch outThe finished dip should stay dry and crumbly — if it's turned wet and pasty you've over-pounded or added too much.
