In a bowl, mix the chili powder, turmeric powder, salt, coriander powder, hing, ginger, garlic and green chili paste with the lime juice - this is the marinade
Wash the fish steaks well and pat them dry using kitchen towels. Apply the marinade on both sides of each steak evenly, in a thin layer. Keep them aside for 15 minutes
On a plate or tray, mix together the semolina and the rice flour. Simultaneously, heat the tawa/frying pan with the oil
Next, dab the fish pieces in the semolina mixture, on both sides, in a thin but even coating. Lower the steaks in the pan over medium heat and fry each of them for 3-4 minutes on each side
Remove on an absorbent kitchen towels and sprinkle chaat masala and coriander leaves on the fried fishes. Serve your delicious surmai rava fry alongside green chutney and sliced onions. Enjoy!
