Meen moilee (Keralan fish curry)

Method

1. To make the sauce, heat 1 tbsp oil in a pan, add the garlic, ginger, chillies and curry leaves, then stir until the leaves begin to crackle.
2. Add the onion and cook over a medium heat for about 5 minutes until translucent. Add the ground turmeric and lemon juice, then stir for 1 minute. Add the coconut milk, bring to the boil and cook for 2 minutes. Season, then set aside.
3. For the fish, heat the other 1 tbsp oil over a high heat in another frying pan. Season the fish fillets and fry, skin-side down, for 1 minute until the skin is crisp. Turn over and fry for 20 seconds until just cooked. Spoon the sauce into 4 shallow bowls and put a fillet in each one. Garnish with coriander and serve.
