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