Cambodia's ancient stirring soup: a light broth of pork, vegetables, and prahok continually stirred during cooking to meld its earthy, savory flavors.
Samlor korko (samlor meaning 'soup,' korko meaning 'to stir') is one of the oldest continuously documented dishes in Cambodian cuisine, its origins traced to the kitchens of the Angkor empire and considered a symbol of Khmer identity. The technique gives it its name: the soup must be stirred almost continuously throughout cooking so the kroeung paste, prahok (fermented fish paste), and vegetables integrate fully into the broth without any single element dominating. The result is a humble but deeply flavorful soup — earthy and slightly funky from prahok, fragrant from lemongrass and galangal, sweet from the seasonal vegetables (pumpkin, eggplant, banana blossom, or whatever the garden offers), and savory from pork. Samlor korko is the soup that Cambodian families come home to, cooked in large pots for gatherings, and eaten at every life event from weddings to merit-making ceremonies at Buddhist pagodas.
Serves 6
Pound or blend lemongrass, galangal, turmeric, shallots, garlic, and kaffir lime leaves into a rough paste.
Place pork in a pot with water and bring to a boil. Skim any foam. Add kroeung paste and prahok. Stir well to combine. Reduce to a medium simmer.
Stirring the prahok into the broth rather than adding it whole distributes its flavor evenly and prevents pockets of intense fishiness.
Add pumpkin and banana blossom after 15 minutes. These take longest to cook.
Stir the soup every few minutes — this is the korko technique. It blends the paste into the broth evenly and is not optional.
Add eggplant, long beans, and palm heart after another 15 minutes. Cook 10-12 more minutes until all vegetables are tender and pork is cooked through.
Add fish sauce and palm sugar. Taste — the soup should be earthy, savory, and gently aromatic. Serve with steamed rice and fresh herbs on top.
Prahok is integral to authentic samlor korko — without it the soup is just vegetable pork soup. Use shrimp paste as a substitute but accept a different flavor.
Use at least 3-4 different vegetables for the characteristic abundance of this soup.
The korko stirring technique matters — stir every 3-4 minutes throughout the 45-minute cook.
Chicken samlor korko: replace pork with chicken thighs for a lighter version.
Vegetarian samlor korko: omit pork and prahok; use mushroom broth and miso paste for umami.
Refrigerate up to 3 days; the flavor deepens. Reheat on the stovetop — add a splash of water as broth concentrates on storage.
Samlor korko is referenced in 13th-century Chinese traveler Zhao Daguan's account of Angkor as a soup made by the common people from fish paste and vegetables. It is considered one of the oldest surviving Cambodian recipes and appears on the menu of the royal palace kitchen documents from the post-Angkor period. The dish's survival through war, famine, and the Khmer Rouge era is a testament to its deep cultural embeddedness.
Prahok is Cambodian fermented fish paste made from crushed, salted freshwater fish — a cornerstone ingredient in Khmer cooking with an intensely savory, funky flavor. It is usually available at Cambodian or Southeast Asian grocery stores.
The korko technique ensures the kroeung paste and prahok distribute evenly through the broth. Without stirring, the paste settles and burns on the bottom, producing bitter, uneven flavor.
Yes — samlor korko is by nature a flexible soup based on seasonal vegetables. Green papaya, lotus stem, morning glory (water spinach), and young bamboo shoots are all traditional additions.
