Preheat the oven to 180°C (160°C fan)/gas mark 4. Line a baking tray with baking paper.
Stir or whisk the soup. In a large jug, whisk together the yoghurt, chickpea flour and 500ml (17 fl oz) of water, the onion, and a pinch of salt.
Peel the vegetables and add the spices. Add the onion and cook for 5 minutes until caramelized.
Add the vegetables and cook for 5 minutes, stirring occasionally.
Using two tablespoons, roll the mixture into balls. Bake for 15-20 minutes until golden and crisp.
Meanwhile, for the tarka, thinly slice the garlic and cut the green chillies in half.
Once the pakoras are baked, add most of them to the soup, saving a few for garnish at the top.
Heat the 2 tablespoons of vegetable oil in a small saucepan. Add the mustard and cumin seeds and cook for 2 minutes until they start to pop.
Add the curry leaves and the green chillies. Add the turmeric and salt, then immediately pour over the soup.
Once the green chillies are bright green, add the garlic. Let it infuse for 5 minutes before ladling into bowls and enjoying.
