Roasting the cauliflower is a great way to add extra flavour and depth to this soup. Perhaps if you're roasting vegetables for your sunday roast, pop some extra cauliflower into the mix and whizz them up using this method and they can make a perfect starter course to a family gathering or dinner party. This works really well with some croutons or if you're having it as a main, try some crusty bread with it.

  1. Preheat the oven to 200C/180C fan/400F/gas 6. Place the cauliflower in a large pan of boiling water and cook for 3 minutes before draining well.

  2. Grind the seeds in a pestle and mortar. Toss the cauliflower florets in 2 tbsp of oil, the spices, chilli and lemon zest. Transfer to two baking sheets, season well and roast for 15 minutes.

  3. Fry onions in the remaining oil for 10 minutes until soft. Reserve a handful of cauliflower and roughly chop the rest, then stir through the onions and cook for a further 10 minutes.

  4. Pour over the lemon juice, stock and milk. Use a stick blender or food processor to whiz until smooth.

  5. Return the soup to a saucepan and bring to the boil. Take off the heat and stir through the cream.

  6. Place the remaining 1 tsp of cumin seeds in a frying pan and dry fry for 2 minutes over a high heat. Sprinkle over the soup and garnish with the reserved cauliflower to serve.
