Sardine Curry/Spicy Tangy Sardine Curry/Mathi Curry

Sardines have a lot of health benefits,the main among them is it lowers the LDL cholesterol as it is rich in omega-3 fatty acids.Therefore it helps prevent heart diseases.And for this reason this fish is there in my dads favorites.Even Mackerels have this quality which is his another favorite and the best part is these fishes are there in plenty in south India and we get these in cheaper rates compared to other fishes there.
Me and my children just don't like Sardines,don't have any particular reason but I  think for my kids its those small bones.But those bones too have the calcium content in them.I am OK with Mackerels,specially love the Ayala varattiyathu in clay pot. 
      In India Umma prepares this curry at least two-three times weekly.This spicy and tangy curry is made using those small sardines and cooked in earthen pot(mann chatti).This curry goes well with rice,Tapioca stir fry or even Parottas.
