Spiced courgettes with curried yogurt

Method

1. For the spice mix, toast the spices in a dry pan for 30-60 seconds until fragrant (take care not to burn them). Remove from the heat, allow to cool, then pound in a pestle and mortar to a coarse mixture. Store in an airtight container. It will keep for up to 1 month – scatter it over grilled meat and veg to add texture and flavour.
2. For the yogurt, heat the oil in a pan and add the mustard seeds and curry leaves. When they start to crackle, quickly add the ground turmeric, sugar and salt. Add this to the yogurt along with the ginger and chilli, then mix well. Adjust the seasoning to taste and set aside.
3. Sprinkle the courgette slices with the oil, salt, black onion seeds and fennel seeds. Cook on a hot barbecue for about 1 minute on each side until just tender. Remove to a large plate. Drizzle with more oil and sprinkle over a little of the spice mix.
4. Scatter over the coriander and sprinkle with the lemon juice. Serve with the yogurt on the side.
