Clean the fish thoroughly and chop into bite-size pieces. Marinate with all the ingredients listed under marination for at least half an hour.
Brush the wired base of the air fryer basket with oil. Spread the fish pieces in the basket and set the temperature to 180°C.
Let the fish cook for 6 minutes. After 3 minutes, shake the air fryer basket or move the fish pieces, using a blunt knife or spoon. This releases the fish pieces from the base.
If you do not have an air fryer, go ahead and deep fry or shallow fry the fish pieces. Alternately, you can even roast them with a little oil in a skillet.
After 6 minutes, transfer the fish from the air fryer to a plate.
Next, take a skillet and add oil to it. Once it gets heated up add the tempering items one by one. Fry for a second and add 2 tbsp of water. When it starts boiling, add the cooked fish pieces to it. Saute so that the fish pieces are fully coated with the tempering.
Transfer to a serving dish and serve with lemon wedges and onion rings
