A Cambodian slow-simmered green stew built on a roasted kroeung paste and prahok, combined with pork and a medley of unripe vegetables and fruits, finished by stirring in fresh herbs.

Identity criteria

  1. 1Roasted kroeung — the lemongrass-galangal-turmeric paste — forms the aromatic base; it must be toasted, never added raw
  2. 2Prahok (fermented fish paste) is the non-negotiable primary seasoning and principal umami source
  3. 3The vegetable body must be specifically unripe or green produce — banana blossom, young jackfruit, Thai eggplant — not mature equivalents
  4. 4Pork, preferably bone-in, is the canonical protein; the bones contribute body to the broth
  5. 5The dish must contain multiple vegetables simultaneously; it is never single-vegetable or purely broth-forward
  6. 6Fresh herbs are stirred in at the final moment — the korko step that names the dish — and must stay bright and barely wilted, not fully cooked

Components

Base

banana blossom (unripe, green)essentialCore vegetable component; must be unripe — ripe blossom is incorrect

young green jackfruitoptionalTraditional and common; provides bulk and mild bitterness; can vary by season and region

Thai eggplant (small round variety)optionalCommon addition; added mid-simmer

winged beans or long beansoptional

Protein

bone-in pork ribs or pork bellyessentialBone is essential for broth body; cut into chunks before simmering

Aromatics

kroeung (Cambodian lemongrass paste)essentialWhole paste of lemongrass, galangal, kaffir lime leaf and zest, turmeric, garlic, shallots — must be roasted before liquid is added

Fat

neutral oiloptionalVehicle for blooming kroeung and prahok

Liquid

water or light pork stockessential

Seasoning

prahok (fermented fish paste)essentialDefining Cambodian fermented condiment; provides salinity, depth, and umami; bloomed in oil before liquid

fish sauceoptionalSecondary seasoning adjusted after prahok is incorporated

Garnish

morning glory (water spinach) or similar leafy greenessentialAdded only in the final minutes

fresh Asian basil and sawtooth corianderessentialThe korko stir-in; must stay vibrant, not wilted through

Technique

Roasting kroeung in a dry pan or with oil before adding liquid
Raw kroeung is sharp and vegetal; roasting caramelizes its aromatics and builds the nutty, deepened base that defines the soup's character — skipping this produces a flat, raw-tasting broth
Blooming prahok in fat before adding liquid
Cooking fermented paste in oil mellows its harsh raw pungency and integrates it evenly into the fat; added directly to water it remains sharp and unrounded
Staged vegetable addition ordered by density and cooking time
Dense vegetables (jackfruit, eggplant) need the full simmer; leafy greens added too early turn to mush — misordering collapses the textural contrast that defines the dish
Final stir-in of fresh herbs (the korko)
The dish's name describes this step; herbs must enter off or at lowest heat and be served immediately — further cooking destroys the brightness and color that signal the dish is alive

Character

Flavour

Texture

brothy with tender pork chunks, vegetables at graduated softness from dense to barely wilted, and bright herb wisps across the surface

Eaten

Everyday Cambodian family lunch or dinner eaten communally; also a centerpiece dish at Buddhist ceremonies, family celebrations, and national cultural events — its presence on the table signals Cambodian culinary identity

When

year-round · best in rainy season when young unripe vegetables and fresh herbs are at peak abundance

Variations & related

Regional variations

  • Samlor Korko with freshwater fish · coastal and riverside Cambodia

    Fish replaces or supplements pork in fishing communities near the Tonle Sap and Mekong

  • Vegetarian temple version · Buddhist temple kitchens throughout Cambodia

    Prahok replaced with soy sauce; loses canonical identity but is a recognized and deliberate monastic variant

  • Ceremonial or royal version · Phnom Penh

    More elaborate kroeung with additional dried spices; sometimes augmented with dried shrimp for deeper umami

Related dishes

  • sibling Samlor Machu

    Another principal Cambodian samlor, but sour-forward with tamarind rather than herb-green and fermented-base dominant

  • sibling Amok Trey

    Shares kroeung and prahok as foundational seasonings; Amok is steamed to a firm custard while Korko remains an open broth stew

  • sibling Kaeng Liang (Thai vegetable soup)

    Related Southeast Asian tradition of multi-vegetable herb broth; different paste structure and no prahok equivalent

  • pairs-with Nom Banh Chok

    Both anchor a traditional full Cambodian family meal; often appear together at ceremonial spreads

Substitutions

  • prahokshrimp paste (kapi)admissible

    Reduces Cambodian specificity but preserves the fermented-seafood character; accepted in practice

  • prahokmiso or soy sauceinadmissible

    Eliminates the fermented fish identity entirely — produces a different dish, not Samlor Korko

  • banana blossomartichoke heartadmissible

    Usable texture stand-in in markets without Southeast Asian produce; flavor profile shifts

  • young jackfruitchayote or green papayaadmissible

    Reasonable substitute for mild flavor and firm texture; stays within the spirit of the dish

  • kroeungpre-made Thai green curry pasteinadmissible

    Fundamentally wrong — Thai paste has a different spice architecture and introduces coconut milk assumptions; breaks Cambodian identity

  • porkchicken thighs (bone-in)admissible

    Acceptable swap producing a lighter, cleaner broth; remains recognizable as Samlor Korko

Common mistakes

  • Adding prahok raw to the liquid without blooming it in fat first, leaving harsh unintegrated fermented notes
  • Using ripe or canned produce instead of specifically unripe green vegetables, eliminating the characteristic bitterness and color
  • Substituting a pre-made Thai curry paste for kroeung, which introduces incompatible flavor compounds
  • Overcooking the final herbs — they must be stirred in off-heat and served immediately or they turn dull and grey
  • Treating it as a single-vegetable soup rather than a medley; the range of textures across multiple vegetables is definitional
  • Under-seasoning with salt alone and neglecting to calibrate fish sauce against the prahok load, producing an imbalanced broth

Provenance

Samlor Korko is one of Cambodia's most ancient soups, widely regarded alongside Fish Amok as a national dish. Its roots trace to pre-Angkor subsistence traditions of combining foraged unripe vegetables with fermented fish paste — both techniques born of preservation and abundance in the Mekong basin. The name literally translates as 'stirring soup,' referencing the final fold of fresh herbs into the pot.
