An authentic Indian specialty cooked with freshly ground roasted spices, caramelised onions, and aromatic herbs in the traditional style.
Rub the fish with half the turmeric and a pinch of the salt, shallow fry lightly, and set aside.
Heat the coconut oil in the same pan and crackle the mustard seeds and curry leaves.
Add the ginger-garlic paste and fry until the raw smell disappears, then stir in the chili powder off the heat.
Return the fish to the pan, pour in the vinegar with the remaining turmeric and salt, and simmer for 5 minutes.
Cool completely and let the pickle rest for a day so the flavours meld.
Serve in small portions as a tangy side with curd rice or kanji rice.
