I used to cook Fish curry or Meen Kulambu and put the fish head in that while boiling. I never know there is a special recipe for Fish Head Curry until I came here. In my Office get together once my colleague ordered this famous Singapore Fish Head Curry and when I tasted, it is something different from our normal Fish curry. Immediately I googled and took the base recipe of Fish head curry from Muthus Curry Restaurant and cooked it that weekend and it was awesome. I bet, if you try this one time, definitely you will keep trying this again and again.

2. In a big kadai or wok, add oil and when it is hot add the fenugreek seeds, cumin seeds, fennel seeds. In 30 seconds gap add the green chilli, curry leaves and garlic.
3. In another 30 seconds, add the onion and fry it. Wait till they becomes translucent. Now add the tomato and sauté them well.
4. Add the ginger paste now and fry till the raw ginger smell goes off. By this time, the oil starts oozing out.

6. Let the tamarind water starts boiling. Add the drumstick and brinjal.

Yummy and Famous Singapore Fish Head Curry is ready. Notes:1. Be careful while adding the chilli powder, salt and coriander powder second time in the gravy, as the fish is marinated already. Sometimes it might be too spicy.2. Also keep in mind we also add the green chillies. So adjust the chilli powder according to your taste buds. (The quantity mentioned, is for my family taste)3. You can also add pepper powder, but it takes little peppery.4. Adding coconut milk, enhances the taste.5. Adding veggies is purely optional, but still it tastes good while adding.6. Always allow to boil the fish curry for 15 min at least and the curry tastes great the next day.Courtesy: http://akilaskitchen.blogspot.com/2015/02/fish-head-curry-how-to-make-singapore.html#ixzz7twHnNY2JUnder Creative Commons License: Attribution Non-Commercial No Derivatives
