Fried fish & tomato curry

Use a sustainable white fish like pollack in this southern Indian-style coconut and tomato curry with fresh coriander
Ingredients
    2 tbsp vegetable oil, plus 2 tsp
    2 onions, thinly sliced
    8 large vine tomatoes, roughly chopped
    4 garlic cloves
    thumb-sized piece ginger, roughly chopped
    3 tbsp Madras curry paste
    165ml can coconut milk
    large handful coriander, finely chopped, plus extra sprigs to serve
    500g pollack fillets, skinned
    6 tbsp plain flour
    basmati rice, to serve
Method
    Heat 2 tsp oil in a pan. Tip in the onions and a pinch of salt. Cook for about 8 mins until soft and golden.
    Meanwhile, blitz the tomatoes, garlic and ginger in a food processor to a smooth purée. Add the curry paste to the onions and fry for 3 mins more. Stir in the tomato mix and simmer for 10 mins until thickened. Add the coconut milk and chopped coriander. Simmer again to thicken.
    Dust the fish fillets in some seasoned flour. Heat the remaining oil in a non-stick frying pan. Cook the fillets, in batches, over a high heat for 1 min or so on each side, until they begin to brown. Carefully place fish in the tomato mixture and simmer until just cooked through. Scatter over coriander sprigs and serve with rice.
