1. You can prepare this fish fry, with any kind of fishes.
2. Marinating the fish is important as it gives more taste to the fish fry recipe. So try to marinate atleast 30 to 40 minutes.
3. Adding corn flour and rice flour, increases the crispiness of the fish and also can reduce the spiciness, when giving to the kids. If you do not like it, you can just omit it.
4. Adding lemon juice, gives a mild tangy flavor to the fish. If you do not like it, you can very well omit that too.
