Clean and cut fish into 1 inch pieces.
Marinate it for atleast 30 mins outside or in refrigerator for 3 - 5 hrs.
Fry fish in oil. Keep it aside.
Saute minced ginger in 6 or 7 tbsp oil.
:- You can use remaining oil from frying fish. But don`t use that, if it is burnt/black etc. Also you can use the same pan used for frying fish.
Add more or reduce oil depending on your health restrictions.
Add onions to it.
When it is soft and golden yellow, add 1/2 tsp chilli powder and 1/4 tsp turmeric powder and saute again.
Add tomatoes, green chillly pieces and curry leaves and saute that until it turns to a nice roast mixture.
Add fried fish to it and mix slowly so that it won`t break.
:- If it looks dry and if you want, you can add more oil.
Mix everything well and cover it.
Cover and cook on low heat for some more time for 15 - 20 mins.
Mix in between and make sure it is not getting burnt and not sticking to the bottom of the pan so that the flavor of different ingrediants will blend together.
ENJOY!!!
