Heat the oil in a pan. Add the seeds and cardamom, and cook until they start to sizzle. Tip in the onion and carrot, and fry for a few mins until colouring and fragrant, then add the tomatoes, ginger, chilli, spices and 2 tsp salt, and cook for another 8-10 mins, stirring occasionally.

Add the stock, bring to the boil, then simmer for 40 mins until the carrots are really tender. Leave to cool slightly, then blend to a smooth soup. Add the lemon juice and some seasoning to taste. Return to the pan, add the milk and warm through. Serve topped with our cashew & coriander salsa and spring onion.
