1Peel the raw bananas and slice them diagonally into thick, fish-shaped pieces.
2Optionally, create a small hole in the center of each slice to mimic the appearance of a fish.
3Blanch the banana slices briefly in boiling water with added salt.
4In a mixer, combine shallots, ginger, green chili, garlic, lime juice, fennel seeds, black pepper, chili powder, garam masala, turmeric, salt, rice flour, corn flour, gram flour, and a splash of water to form a fine paste.
5Coat the blanched banana slices thoroughly with the prepared spice paste and let them marinate.
6Shallow fry the marinated banana slices in a pan with hot oil until crispy.
