Thai Green Curry (Kaeng Khiao Wan)

A fragrant, gently spicy Thai curry of chicken and vegetables simmered in green curry paste and coconut milk. With store-bought paste it's a 25-minute one-pot dish, perfect over jasmine rice.

Variations

  • Shrimp or beef: Swap the chicken for shrimp or beef.
  • Vegetarian: Tofu, mushrooms, and veg, with soy sauce instead of fish sauce.
  • Red/yellow curry: Just change the paste for a different curry.
  • Milder: Use less paste and more coconut milk.

Tips

  • Crack the coconut cream first — frying the paste in the separated oil blooms the aroma.
  • Fry the paste well to cook off the raw edge for deeper flavor.
  • Balance fish sauce, sugar, and lime for salty-sweet-sour harmony.
  • Add the basil and lime leaves at the end to keep them fragrant.
  • Pastes vary in saltiness, so season last.
More detail and the reasons why (5)
  • One to two minutes here, where a rempah gets fifteen. Laksa fries its paste for 15-20 minutes, rawon for eight to ten, mee rebus for eight. This recipe takes one to two, and that is not carelessness — it is what the paste is made of. The fork in the road is the one that separates it from massaman curry: a heavy dose of toasted cinnamon, clove, cardamom and star anise sets massaman apart, while a green curry paste toasts only a little coriander seed, cumin and white pepper and is built on fresh herbs.
  • Fresh aromatics have the least tolerance for heat of anything that goes into a paste. Coriander, basil and their kind are delicate herbs that belong off the heat, or in the last thirty seconds, because their aroma compounds start escaping well below the boil (fresh herbs). Dried chilli, shallot and belacan need time and heat to give theirs up; green chilli, lemongrass stems, kaffir leaf and coriander root hand it over within a minute and then start losing it. So the length of "fry the paste until it is fragrant" is set by the ingredient, not by the dish.
  • Then why fry it at all. Because aroma dissolves in fat and not in water, which is the fact kaeng som is built on — that curry has no fat in it anywhere and pounds its paste far longer to compensate. And the fat does not only extract, it holds: what would leave for the air in an open pan is captured in the oil and then carried through the whole pot. That is what the cracked coconut cream is for, and why a spoon of plain oil is an honest substitute rather than a compromise.
  • The green is chlorophyll, and chlorophyll is the pigment acid destroys. As in blanching, heat releases organic acids from the cells, those acids strip the magnesium out of the chlorophyll, and the colour shifts to olive and then to yellow. That is why the whole simmer here is under ten minutes, and why the ingredients carry kaffir lime leaves rather than juice — the aroma without the acid. Squeeze the lime into the bowl instead.
  • Tear the basil; do not take a knife to it. Chopped basil oxidises where the blade cut it, turns black, and leaves its aroma on the board. Off the heat and torn by hand is the whole of step 6.
