Spices, chilli powder, and turmeric powder make tasty Indian fish pickle. Fried fish is soaked in a tangy vinaigrette with crispy fried curry leaves for extra aroma. Depending on the region, it may be known as fish pickle or fish achar.
In Kerala, it’s known as Mathi Achar, made with sardine fish (mathi). While there is also a Western-style fish pickle, the spicy taste of the Indian fish pickle stands out.
