Tom Kha Gai: Thailand's Most Comforting Soup

Tom Kha Gai translates literally as 'galangal chicken soup' — and galangal is the key. Not ginger, which is often mistakenly substituted. Galangal has a sharper, more citrusy flavor that gives this soup its distinctive character. It is one of the most important aromatics in Thai cooking.

The soup is built on a base of coconut milk, lemongrass, galangal, and kaffir lime leaves — four ingredients that together create one of the most recognizable aromas in Southeast Asian cuisine. The broth should be rich and silky, with a gentle heat from fresh chilies and a bright sourness from lime juice added at the end.

For four servings, you will need: 800ml of premium coconut milk, 400ml of chicken stock, 300g of chicken breast or thigh (sliced), three stalks of lemongrass (bruised), five slices of galangal, four kaffir lime leaves (torn), three fresh chilies (bruised), two tablespoons of fish sauce, one tablespoon of lime juice, and a handful of fresh coriander.

Bring the coconut milk and stock to a gentle simmer. Add the lemongrass, galangal, kaffir lime leaves, and chilies. Simmer for five minutes to infuse the broth. Add the chicken and cook for eight to ten minutes until just cooked through. Season with fish sauce and lime juice. Finish with fresh coriander and serve immediately.

The aromatics — lemongrass, galangal, kaffir lime leaves — make all the difference. Fresh is best, but high-quality dried versions work well too. All of these ingredients are available at PIN Family Mart on Central Avenue.
