Drain the Water (Crucial Step): Wash the Bombil fish thoroughly. To ensure they don't get soggy, wrap the fish in a clean cotton cloth and place a heavy weight on it for a few minutes. This presses out the extra moisture, which is key for a crispy fish fry.
First Marination: Take the dried fish in a plate. Apply lemon juice (or Kokum Agal) and the crushed ginger-garlic. Rub it well on both sides. Let it rest for 10–15 minutes.
Apply Dry Spices: In a small bowl, mix turmeric, red chilli powder, coriander powder, garam masala, and salt. Apply this dry spice mix generously over the marinated fish pieces.
Prepare the Coating: In a separate plate, mix Fine Rava (Semolina) and Rice Flour. Season this coating with a little salt, turmeric, and chilli powder to ensure the outer layer is flavorful.
Coat the Fish: Take each spiced Bombil piece and roll it in the Rava-Rice flour mixture. Press gently so the coating sticks well. Shake off any excess.
Shallow Fry: Heat oil in a tawa (flat pan) or skillet. Once the oil is medium hot, place the fish pieces gently. Do not overcrowd the pan.
Cook to Perfection: Fry on medium heat for the first 2 minutes. Once the coating sets, flip the fish.
The Crisp Trick: After flipping, lower the heat to sim/low. Let the Bombil fry slowly for about 8-10 minutes total. This slow cooking draws out remaining moisture and makes the outer layer extremely kurkurit (crispy).
Serve: Once golden brown and crisp on both sides, drain excess oil and serve hot.
