Tom kha gai (chicken in coconut-galangal soup)
Central Thai home cooks make tom kha as one of the dishes at a shared dinner, spooned over rice rather than drunk as a starter, and Bangkok restaurants serve it in a bubbling fire pot. Galangal, lemongrass and kaffir lime leaf are simmered in coconut milk with chicken and mushrooms, then seasoned at the end with fish sauce and lime, so the soup is creamy, sour, salty and only gently hot. For a vegetarian version (tom kha het), use 400 g mixed mushrooms and firm tofu, vegetable stock and light soy sauce instead of fish sauce. Chef's tip: add the lime juice off the heat; boiling lime turns bitter and dulls the whole pot.
