Rui Posto 

(Rohu Fish in Poppy Seed Paste) 

Rui posto has made a very dear place in Bengal kitchen from the old ages. Not much spices, no big time, this dish is purely a bliss to cook and have!! 

You need 6 rohu fish fillets (marinated with turmeric and salt, kept aside for 10 minutes and fried in mustard oil). 

Make a paste using 4 tbsp of poppy seeds, 2 green chillis (I'm going to add some grated coconut too tomorrow).

Make the paste smooth. 

Heat mustard oil in a pan, add kalonji 1/2 tbsp and then fry one medium sliced onion until soft.

Add the paste, stir for a little time. (Don't take too much time otherwise you will kill the taste of poppy, just 1 minute will do.). 

Add water as you want, depending on the thickness of gravy, add salt. 

Let it come to boil. 

Add the fried fish fillets.

And don't forget adding two slit green chillis.

Boil for sometime on low heat. 

Done. 

Spread some mustard oil before serving. 

Rui posto is ready to eat and it tastes best with hot stimmed rice.
