About Tom Yum Goong
Thailand's most internationally famous soup: a clear, fierce broth of galangal, lemongrass, kaffir lime leaves, chilli and lime juice with whole prawns; the balance of the four flavours (hot, sour, salty, fragrant) must be simultaneous and equal; the creamy version (tom yum nam khon) adds evaporated milk; the clear version (tom yum nam sai) is brighter and more intense.
Thailand's Most Famous Soup
Tom yum goong is Thailand's most famous soup: a clear, fierce broth of galangal, lemongrass, kaffir lime leaf, chilli and lime juice, with plump prawns. Its hallmark is balance, hot, sour, salty and fragrant all at once and in equal measure. It is bright, aromatic and bracing.

The Balance
The whole dish lives or dies on the balance of its four flavours. Too much lime and it becomes sour soup; too much fish sauce and it is merely salty; the cook's skill is in the ratio. When it is right, no single flavour dominates and all four arrive together. That equilibrium is the art of tom yum.
Clear or Creamy
There are two main versions. The clear nam sai is sharper and more intense, letting the aromatics ring out; the creamy nam khon, enriched with evaporated milk or chilli paste, is milder and rounder. Both are authentic, but the clear version shows the soup's flavours most plainly.
The Aromatics
The fragrance comes from galangal, lemongrass and kaffir lime leaf, which are simmered for flavour but not eaten, left in the bowl to be set aside. Bird's eye chilli brings the heat and lime the sourness, with fish sauce for salt. Concentrated and clear, tom yum is one of the most vivid single statements of flavour in Thai cooking.
What to Expect
The tom yum arrives in a clay pot, still boiling. The lemongrass and galangal float on the surface. The first spoonful hits sour, then hot, then the kaffir lime fragrance. The prawn is plump and just cooked.
Why Try It
Tom yum is Thai cooking's most concentrated single flavour statement, five aromatics producing four sensations in one clear broth.
Insider Tips
- The nam sai (clear) version is more flavourful than the creamy version, start there.
- The lemongrass and galangal are not eaten, they're for flavour only.
- Balance is everything: if it tastes one-dimensional, one element is dominant.
