Marinate the fish with two to three teaspoon turmeric powder,a tablespoon salt and lime juice.In between prepare the curry paste adding all the ingredients mentioned above and as showed in the picture i.e ginger,garlic,onion,red dry chillies,coriander powder,cumin seeds,cloves,cardamom,cinnamon in a mixer grinder..add little water and make a smooth paste..

Now in a thick aluminium kadai (don’t use nonstick skillet otherwise the taste will vary) fry those marinated fish in smoking hot mustard oil i.e when oil start releasing smoke is the right time to drop fishes slowly and carefully..if the oil is not smoking hot the pieces will get stuck to the bottom of the kadai..I prefer to fry these fishes until the colour turns slight brown in colour..this way they taste more crispy..

After removing all fried fishes add in cumin seeds and bay leaves,let it crackle.Then add in some potatoes(this is a typical way of preparing fish curry in Bengal)..fry them till golden brown.Now add in curry paste.

Keep frying them together in a low or medium flame..add in some kashmiri red chilli powder to achieve this reddish colour in the curry,add turmeric powder.Keep frying until oil is released from the spices,as you can see in the picture.

Now add sliced tomatoes and salt as par your taste,cook them for five minutes until the tomatoes are slightly tender..Now add in water and close the lid.let it boil.Now check weather the potatoes are properly cooked or not.When the potatoes are tender add in all the fried fish and cook for five more minutes in high flame..Fish curry is ready to be served..
