Tom Kha Gai (Coconut Galangal Chicken Soup)

Tom kha gai is central Thai, associated with both the court tradition and the domestic kitchen. The coconut milk base is gentler and more accessible than tom yum for non-Thai palates — it was among the first Thai preparations to achieve international recognition in the restaurant diaspora, which has somewhat obscured its Thai context behind an oversimplified reputation as 'creamy soup.'

A coconut milk soup of chicken, galangal, lemongrass, and kaffir lime — richer than tom yum (coconut milk provides the fat base rather than a clear broth), gentler in heat, and with a sweet creaminess that allows the aromatic herbs to register differently than they do in the acid-forward tom yum environment. Tom kha's defining aromatic is galangal (kha) — the soup is named for it, and the galangal's resinous, slightly medicinal, distinctly Southeast Asian character is more prominent and more appreciated in this mellow, coconut-cream context than in any other Thai preparation.
