Wash prawns, devain and mix with tamarind juice, red chilly powder, turmeric powder, green chilly slit, ginger (cut into pieces) and mango (cut into cubes) :-You can reduce the tamarind if it is too sour since we are adding mango also

Cut drumstick into 4 pieces each and boil in water until half cooked :-Drumstick takes long time to cook than prawns.

Add the prawn with masala and cook adding salt until prawns are tender.

Grind coconut nicely with 2 small onions into a nice paste and add this to the cooked prawns

Add enough water to give a semi loose gravy consistency.

Add curry leaves to this and bring to boil for 1 or 2 minutes and remove from fire.

Heat coconut oil in a kadai.

Add mustard and finely cut small Onion.

Fry until onion turns golden brown and add to curry.

Mix well.

:- This is a very good curry when taken cold with rice or chappathy.
