Doi Ilish (Hilsa Fish in Yoghurt Gravy)

Marinate the fish with yoghurt, salt, turmeric powder, mustard oil and chopped green chilies for 10 minutes.

Heat mustard oil in a pan and temper with nigella seeds and slit green chilies. Saute for a few seconds.

Add the marinated fish and cook, covered on a low flame for 4-5 minutes. When done add the remaining mustard oil and coriander leaves.

Mix gently and switch off the flame. Serve with hot steamed rice.
