Method:
Marinate the fish pieces with salt and turmeric powder; keep aside for 15 minutes.
Blend all the ingredients for the spice paste; add a few drops of water if necessary.
Heat ghee and oil in a wide pan; shallow fry the fish pieces till half done. Keep aside.
In the same pan, add the spice paste and sauté on low heat. Sauté till the spice paste browns lightly and gets aromatic. Do not hurry up this step as this lends the main flavour to the dish. Sauté for around 15 minutes on low heat.
Add the beaten yoghurt and mix in well. Next, add the saffron milk and mix thoroughly.
Add enough water to make a thick gravy. Bring to boil and then add the fish pieces.
Simmer gently for about 10 minutes (add more water if too thick).
Remove from heat and garnish with chopped coriander leaves.
Serve warm with steamed basmati rice.
