Chettinadu Fish Fry is a delicious and crispy South Indian dish that is perfect as an appetizer or a side dish. The fish is marinated in a mixture of spices like red chili powder, turmeric, coriander powder, and lemon juice, which gives it a tangy and spicy flavor. It is then coated with a batter made from rice flour and deep-fried until golden brown. The result is a crispy and flavorful fish fry that pairs well with mint chutney or tomato ketchup.
