Gaeng liang (peppery pumpkin and lemon basil soup)
Older cooks in Ayutthaya and the central plains make this soup for new mothers and anyone feeling run down: a cloudy broth of pounded shallot, white pepper and krachai (fingerroot), packed with pumpkin, baby corn, sponge gourd and handfuls of lemon basil. It is eaten as one of several dishes with rice at a home meal, never as a creamy starter. The everyday version pounds dried shrimp and shrimp paste into the base and seasons with fish sauce; here dried shiitake and tamari give the savouriness, so it is vegan. Chef's tip: add the lemon basil off the heat at the very end; boiled basil turns black and loses the peppery perfume the soup is named for.
