Cook jackfruit seed with water for a whistle in pressure cooker.(Seed will be hard so cook it for a whistle before adding to curry). Peel off the outer white transparent shell, cut into half and keep aside.
Grind coconut with little water to a smooth paste.
Crush shallots and ginger and keep it ready
Clean drumstick and cut into pieces. Adding prawns is optional, you can simply skip it if not desired.
In a pan (I prefer claypot while preparing traditional kerala cuisines which further increases the taste) add drumstick, jackfruit seed, prawns, ¼ tsp turmeric pdr, 2.5 tbsp chilli pdr, 1 tbsp coriander pdr.
Add 1 cup water. Mix everything, cover and cook till the water reduces.
At this stage add raw mango pieces and salt. If you prefer extra tangy add more of raw mango.
After about 5 min add crushed onion and sauté for 10min.
Add grinded coconut and after a boil switch off.
In another pan splutter mustard, small onion, curry leaves, 1 red chilli, ½ tsp chilli pdr and add to the curry mixture. Close and keep till its ready to be served.
Goes good with rice.
