1. Take a bowl and add all the spices, egg, flour and water (1 cup approx or as you need) to make a smooth paste. The density of batter should not too thin or thick. If you drop the batter from spoon it should easily drop and does not stick to the spoon.
2. Dip fish pieces in the batter and leave for an hour in a refrigerator so that all flavors absorb into the fish.
3. In a deep frying pan pour oil and heat it well. When the oil becomes warm put fish pieces in the heated oil and fry on medium heat for 8-10 mins or until fish becomes golden brown in color.
