Wash the fish well using ashes and lemon then marinate it powder ginger and salt allow it to stay for 30 minutes then heat some oil and fry it then keep aside.

In a pan add some oil add sliced onions and garlic and ginger paste shallow fry it then add the seasonings add the fish and stir occasionally for 5_6 minutes then off the heat and serve enjoy! I serve mine using fried potatoes
