ជំនួស · Substitutions
When you can’t get the real thing
Stocking a Khmer pantry from scratch isn’t always easy, and some ingredients — prahok, fresh kroeung aromatics — are genuinely hard to find abroad. Here’s what to reach for instead, told honestly. Every swap is rated for how close it actually gets, with a note on what it costs you, because a substitution that changes the dish should say so.
គ្រឿងផ្សំ
Fermented & salty
The funky, savory backbone of Khmer cooking. A couple of these have decent stand-ins; prahok genuinely doesn’t.
Prahokប្រហុក
Get the real thing →Fermented freshwater fish paste — the deep, funky umami under samlor, dips, and stir-fries. There is no true equal.
Fish sauce + a little white miso1 tbsp fish sauce + 1 tsp miso per 1 tbsp prahok
The miso brings the fermented body, the fish sauce the funk. A polite stranger doing prahok’s job — close enough to cook with, not close enough to fool a Cambodian.
GoodAnchovy pastestart with half, then taste
Salty, fishy, fermented — the right neighborhood. Thinner and less complex than prahok, and it lacks the barnyard depth, but it holds a dip together.
GoodFish sauce aloneto taste for salt
Gets you salt and a whisper of the marine note, none of the ferment. Use only when a recipe needs a background hum, never where prahok is the point.
Last resort
Fish sauce (tuk trey)ទឹកត្រី
Get the real thing →The everyday salt of the Cambodian kitchen — salts, rounds, and deepens nearly every savory dish.
Thai or Vietnamese fish sauce1:1
Effectively the same product from the next kitchen over. Buy whichever your grocer stocks; look for a short anchovy-salt-water label.
ExcellentSoy sauce + a pinch of salt1:1, then salt to taste
For a vegetarian dish or a fish allergy — savory and salty, but darker and without the marine lift. Add a little sugar to round it.
GoodMushroom or vegan “fish” sauce1:1
The best plant-based option — glutamate-rich seaweed and mushroom versions get surprisingly close.
Good
ផ្អែមជូរ
Sweet & sour
The sugar-and-acid balance that makes a Khmer dish sing. Get the ratio right and a rough swap still works.
Palm sugarស្ករត្នោត
Get the real thing →Sap of the sugar palm, boiled to a soft caramel — rounder, less sweet, and more mineral than cane sugar.
Light brown sugar1:1
The molasses in brown sugar mimics palm sugar’s caramel depth. Slightly sweeter and one-note, but genuinely close and always in the cupboard.
GoodCoconut sugar1:1
Often the same thing under a different name — made from palm or coconut sap. The closest supermarket swap by far.
ExcellentWhite sugar + a drop of molasses1 cup sugar + 1 tsp molasses
Covers the sweetness and fakes the color; misses the rounded, faintly smoky edge. Fine in a pinch.
Last resort
Tamarindម្ជូរ
Get the real thing →The fruity, mellow sour in samlor machu and dipping sauces — tangier than vinegar, softer than lime.
Lime juice + a little brown sugar1 tbsp lime + ½ tsp sugar per 1 tbsp tamarind
Lime is sharper and brighter than tamarind’s round, dried-fruit sourness; the sugar softens it toward the right shape. It reads as a different acid, but it works.
Last resortAmchur (dried mango powder)start small
Fruity and sour in tamarind’s family — closer than lime, if you happen to keep it.
Good
Kampot pepperម្រេចកំពត
Get the real thing →The GI-protected pepper of the southern coast — floral, warm, and citrus-edged, a world away from dusty pre-ground pepper.
Tellicherry black pepper1:1, freshly ground
The best widely available pepper — large, ripe, aromatic berries. Less floral than Kampot, but grind it fresh and it holds its own.
GoodAny freshly ground whole black pepper1:1
Fresh-ground beats pre-ground every time, but ordinary pepper misses the perfume that makes Kampot worth the fuss. Serviceable, not special.
Last resort
គ្រឿង
Kroeung aromatics
The pounded paste at the heart of Khmer cooking. These are the notes that make it taste like Cambodia and not the next country over — swap them carefully.
Galangalរំដេង
Get the real thing →The sharp, piney, medicinal root in kroeung — related to ginger but not remotely a stand-in for it.
Fresh ginger1:1, honestly imperfect
The truth: ginger is warmer and sweeter, galangal sharper and more resinous. Ginger will not taste like galangal — it tastes like ginger. Use it only if you must, and don’t expect the same dish.
Last resortDried galangal, rehydratedsoak, then pound
Milder than fresh but the real aromatic — far closer than any ginger swap. Soak in warm water before pounding into kroeung.
Good
Kaffir lime leafស្លឹកគ្រូច
Get the real thing →The bright, floral citrus perfume threaded through amok and kroeung — its own aroma, not just “lime.”
Lime zestzest of 1 lime per 4 leaves
Gets the citrus top note; misses the specific floral, slightly bitter edge of the leaf. The best easy swap in a fresh dish.
GoodBay leaf + lime zest
The bay adds an aromatic backbone the zest lacks. A stopgap for a cooked dish — grow a makrut lime tree if you love this food.
Last resort
Holy basilជីរនាងវង
The peppery, clove-scented basil in stir-fries — hotter and more savory than the sweet basil most stores carry.
Thai basil1:1
More anise, less pepper, but in the right family and far easier to find. The go-to swap when holy basil isn’t around.
GoodSweet Italian basil
Softer and sweeter, none of the clove-pepper heat. It reads as basil, just not the right one.
Last resort
ត្រី និងម្សៅ
Wraps, fish & starches
The structural swaps — what to wrap in, which fish to fry, which noodle to soak — when the exact one isn’t at hand.
Banana leafស្លឹកចេក
Get the real thing →The wrapper and steamer-liner for amok, num ansom, and grilled parcels — it perfumes the food faintly as it heats.
Parchment paper
Holds the shape and steams cleanly for amok cups and parcels. You lose the faint grassy aroma the leaf gives — but structurally it does the job.
GoodParchment wrapped in foil
For grilling: parchment against the food, foil outside for strength and to hold the fold. Keeps the leaf’s function if not its scent.
Good
Freshwater fishត្រី
The river and Tonlé Sap fish — snakehead, catfish, featherback — at the center of amok, samlor, and grills. Firm, sweet, low-oil flesh.
Catfish1:1
A freshwater fish itself — firm, mild, and widely farmed. The closest and most honest swap for most river-fish dishes.
ExcellentTilapia1:1
Mild and easy to find; a touch softer, so handle it gently in a curry. Perfectly good for amok.
GoodBarramundi1:1
Firmer and slightly richer; excellent grilled or in a robust samlor. A step toward saltwater but a fine stand-in.
Good
Rice noodlesនំបញ្ចុក
Get the real thing →From the fresh fermented strands of nom banh chok to dried kuy teav sticks — the noodle under most Khmer soups and salads.
Dried rice vermicelli (bun)soak to soften
The everyday stand-in for fresh nom banh chok — thinner, but the same rice-noodle character. Soak in warm water, then a brief blanch.
GoodDried flat rice stickssoak, then blanch
For kuy teav specifically — the intended noodle in dried form. Medium width is the all-rounder.
Good
Coconut creamខ្ទិះដូង
Get the real thing →The thick, rich top of the coconut — the finishing richness spooned over amok and stirred into sweets.
The cream skimmed off canned coconut milk
Chill a can of full-fat coconut milk, then spoon the firm layer off the top — that is coconut cream. Effectively free if you already have milk.
ExcellentCoconut milk, reduced
Simmer full-fat coconut milk down until it thickens and the oil starts to split. More work, but it gets you there.
