Thai Green Curry (Gaeng Keow Wan)

Green curry (gaeng keow wan) uses fresh green chillies in the paste — it is typically the most aromatic and can range from mild to very hot depending on the paste. Red curry (gaeng daeng) uses dried red chillies — deeper, earthier flavour, consistently hot. Yellow curry (gaeng garee) uses dried chillies plus turmeric and more cumin and coriander — the mildest and closest in spice profile to Indian curry. Green curry generally has more herbs (lemongrass, galangal, kaffir lime) and a brighter, more citrus-forward character; red curry is richer and more deeply spiced.

Three most common causes. First: the curry paste was not fried long enough in the coconut cream — the fat must separate and the paste must fry dry before liquid is added. Second: insufficient fish sauce — fish sauce is the salt and the umami of the dish; under-salted curry tastes flat. Third: palm sugar was omitted — the sweetness balances the heat and acidity. Taste the curry at the end and add fish sauce a teaspoon at a time and sugar a pinch at a time until the flavour rounds and deepens. A squeeze of lime at the very end also lifts flat curries dramatically.

Yes. Replace chicken with firm tofu (press it first, cube and pan-fry until golden for better texture), or use mixed vegetables — courgette, baby corn, bamboo shoots, and mushrooms work well. Replace fish sauce with soy sauce or tamari in equal quantity (the flavour is slightly different but the seasoning principle is the same). The green curry paste must be vegan — many store-bought pastes contain shrimp paste. Maesri brand is commonly available without shrimp paste; check the label. Coconut milk and all other ingredients are already plant-based.

Kaffir lime (makrut lime) leaves are the double-lobed leaves of the makrut lime tree, used in Thai, Lao, and Indonesian cooking for their intensely citrusy, floral fragrance. They are used whole to infuse flavour (not eaten) or shredded very finely as a garnish. They are available fresh or dried at Asian grocery stores, and freeze extremely well. Substitutes in order of preference: dried kaffir lime leaves (significantly less aromatic); strips of lime zest (peel only, no white pith — use one lime per 4 leaves); lemongrass. No substitute fully replicates the specific floral-citrus character.

Store the curry (without rice) in an airtight container in the refrigerator for up to 3 days. Green curry actually improves overnight as the flavours integrate. To reheat: warm gently over low heat, stirring — do not boil, as this can cause the coconut milk to separate and toughen the chicken. If the sauce has thickened too much in the fridge, add a splash of coconut milk or water to loosen. Always add the Thai basil fresh when reheating — adding it during storage causes it to blacken and lose flavour.
