To begin making Bengali Aam Chingri Recipe (Prawn Mango Curry Recipe), get prep with all the ingredients and devein prawns.

In a mixer grinder, grind the mustard seeds with 1 green chillies, grated fresh coconut and a little water, to make a smooth paste and keep aside.

Heat oil in a pan add one green chillies (slit). When the green chillies sizzle and splutter, add the prawns.  Saute on low heat for a couple of minutes or till the prawns turn a little coral in colour.

Add the grated raw mango and a pinch of salt. Keep mixing carefully and lightly to not make it any mushy; saute till the raw smell of the mango is gone (approximately 2 minutes).

Add the mustard paste, turmeric powder and kashmiri red chili powder. Give it a good mix and cook on low till it coats the prawns.

Add coconut milk, salt and jaggery; mix well and cover the lid and let the Prawn Mango Curry simmer on low till all the milk is evaporated and the gravy coats the prawns.

Taste check and switch off. Adjust spices if needed and cook further if required, till done.
