Topse fish fry, also known as mango fish fry, is a popular Bengali dish made with fresh topse fish marinated in a flavorful spice mix and then shallow-fried until crispy. The fish has a delicate and flaky texture with a mild sweet taste, which pairs perfectly with the aromatic spices. This dish is easy to prepare and makes for a delicious appetizer or side dish. Serve the topse fish fry hot with a squeeze of lemon and some mint chutney for a burst of flavors.
