60ml (2fl oz) vegetable oil
1 tbsp yellow mustard seeds
1 large onion, finely chopped
15g/3 cloves garlic, finely crushed
30 fresh curry leaves
2 tsp Kashmiri chilli powder

Heat the oil in a heavy-based saucepan or karahi over a medium heat. When hot, add the mustard
seeds and fry for 30 seconds, then stir in the onion and garlic and fry gently for about 10 minutes
until softened and lightly golden.
Add the curry leaves, chilli powder, coriander and turmeric and fry for two minutes, then stir in the
tomatoes, tamarind liquid, green chillies and salt and simmer for about 10 minutes until rich and
reduced.
Add the fish, cook for a further five minutes or until just cooked through, and serve with plain rice.
