Step 1

If using kokum, wash and then soak them in 400ml (1 ½ cups) water until needed. Heat the oil in a large saucepan over medium high heat and add the fenugreek seeds and curry leaves. Infuse these ingredients in the oil for about 30 seconds. Add the chopped onions and fry until lightly browned, about 5 minutes. Stir in the sliced garlic and ginger and fry for a further minute and then add the chilli powder, coriander powder and turmeric powder and stir to combine.

Step 2

Now add the chopped tomatoes and the kokum and the water they were soaked in OR 2 tsp tamarind concentrate and 400ml (1 ½ cups) water. Bring this to a boil and simmer for 5 minutes. Then add the fish pieces and cook, covered over medium heat for 10 to 15 minutes or until the fish is just cooked through. A little more water could be added if you prefer a thinner sauce. Add a handful more curry leaves (optional) and stir them in and then add salt to taste to serve.
