Fish Mappas

fish mapas 1

Fish mappas is dish from Kerala with sweet flavour of coconut milk and a slight pungent taste of mustard powder. Mildly spiced with crushed peppercorns.

I have used store bough coconut milk and instead of mustard powder I have used 1 tsp of regular mustard sauce. Only reason for this is that mustard powder was out of stock!

In the tempering, I have added some whole garam masala spices like cloves and green cardamoms. You can leave them out for a lighter version. Also, I have pan-fried the marinated fish pieces instead of cooking it in the gravy.
