The fragrant combination of lemongrass and ginger fills the kitchen as the Thai coconut broth simmers gently. This dish perfectly balances delicate cod with rich Asian flavors, creating a taste experience reminiscent of Bangkok's vibrant markets.
I first discovered this dish during a trip to Thailand, where a local chef taught me that success lies in balancing flavors while cooking the fish with care.
Essential Ingredients Guide
