Spices in Cambodian cooking
Quick answer
Khmer cooking, built on fresh herb pastes called kroeung and on prahok, with far less chilli heat than its neighbours.
Characteristic spices: Lemongrass, Galangal, Turmeric, Makrut lime leaf, Fingerroot, Black pepper
How spices are used in Cambodian cooking
The sequence rather than the list: when spices go in, in what state, and what the step is for.
Most dishes start from kroeung, a paste of lemongrass, galangal, turmeric, makrut lime and garlic pounded fresh in a mortar, fried briefly or mixed raw into a marinade. The savoury base comes from prahok, fermented fish paste, rather than from shrimp paste. Heat is not built into the paste: chilli is added at the table or through the red kroeung used in curries, which is the clearest difference from Thai cooking. Black pepper, from Kampot on the southern coast, is used fresh in green bunches as well as dried.
Combinations documented in Cambodian cooking
The same pairings the food pages show, gathered here by cuisine, each with its reason.
White fish
ClassicFish amok — fish steamed in banana leaf with yellow kroeung, coconut milk and egg — is the best-known Khmer dish and the clearest showcase of the paste: lemongrass and makrut lime scent the fish, and there is no chilli heat at all.
How: Fish amok
Beef
StrongGrilled beef skewers marinated in yellow kroeung, sold from street grills across Cambodia, are the everyday use of the paste on meat.
How: Grilled beef skewers
Chicken
StrongChicken in samlor, the Khmer sour soups and stews, and chicken curry with red kroeung and coconut milk are both built on the paste.
How: Samlor with chicken; Khmer chicken curry
Beef
StrongLemongrass leads the marinades for grilled beef in Khmer and Vietnamese cooking, where its citrus lifts charred, fatty meat.
How: Grilled beef skewers; Lemongrass beef
Blends used in Cambodian cooking
The blends whose own pages name this cuisine as their home.
Profiles
Lemongrass
The stem base of a tropical grass, used fresh, dried or as a paste for a clean citrus aroma that has none of the acidity of lemon. It is fibrous enough to be inedible in most preparations, so it is usually bruised, infused and removed rather than eaten.
Galangal
Not a kind of ginger. It is a separate genus in the same family, and the difference is not one of strength — galangal is piney, sharp and almost medicinal where ginger is warm and citric, and swapping them changes what a dish tastes of.
Turmeric
The boiled, dried and ground rhizome of Curcuma longa, valued primarily for the intense yellow of its curcuminoids and secondarily for an earthy, bitter, faintly musky flavour.
Makrut lime leaf
The double-lobed leaf of Citrus hystrix, used whole or shredded across Southeast Asia for an intense lime-peel aroma quite unlike lime juice. It contributes fragrance rather than sourness, freezes almost perfectly, and dries very badly — which is why the dried leaf on most spice shelves is a poor buy.
Fingerroot
A Southeast Asian rhizome whose slender finger-like tubers give it its name. Peppery, bitter and faintly medicinal, between ginger and galangal but genuinely neither, it is a required aromatic in Thai jungle curry and in the Thai fish curries.
Black pepper
The dried unripe fruit of the vine Piper nigrum, picked green and dried until the skin blackens and wrinkles. Its pungency comes from piperine, not capsaicin, which is why the Scoville scale does not apply to it.
Cambodian is treated here as a grouping, not a monolith. Where regional traditions within it differ meaningfully, the individual spice profiles record them separately rather than merging them.
