✔ Creamy but not heavy
✔ Bright and refreshing
✔ Slightly tangy
✔ Naturally comforting

Many variations of coconut fish soups come from Southeast Asia. One of the most famous is Tom Kha Soup, a Thai soup known for its coconut milk base, aromatic herbs, and citrus notes.

While traditional versions include ingredients like galangal and lemongrass, this recipe simplifies the process while keeping the same vibrant flavor profile.

Fresh citrus makes a huge difference.
