When making lemongrass grilled fish, you need to select clean and fresh tilapia, apply fresh lemongrass, chili powder and salt evenly on the fish after boiling water, and marinate for one hour. Afterwards, when roasting with different degrees of ripeness, brush with secret sauces and seasonings. Put the lemongrass segments on the fish maw, cover with banana leaves, roast until golden on both sides, and then sprinkle with local special spices. The freshness of fish mixed with the fragrance of lemongrass in the mouth is endless aftertaste.
