🥥 What is Thai Coconut Soup (Tom Kha)?
Tom Kha Gai, which translates to “boiled galangal chicken,” is a creamy, slightly spicy soup traditionally made with chicken, coconut milk, galangal root, lemongrass, kaffir lime leaves, and Thai chilies. The soup is known for its perfect balance of creamy, sour, spicy, and savory notes. While chicken is the classic protein, modern variations include shrimp (Tom Kha Goong), tofu, or mushrooms.
