Chettinadu Fish Fry is a popular seafood dish from the Chettinad region of Tamil Nadu, South India. It is made by marinating fish fillets in a mixture of spices and then shallow frying them until crispy and golden brown. The marinade is made with a blend of spices like red chili powder, turmeric, coriander powder, and cumin powder, along with ginger-garlic paste and lemon juice. The fish is then coated with a mixture of rice flour and semolina before frying, which gives it a crispy texture. This delicious and spicy fish fry is perfect as an appetizer or as a side dish with rice or roti.
