Serves 225 minutesGluten-freeKetoDairy-freeAnti-inflammatoryRich in protein

Ingredients

  • 400 ml tin coconut milk
  • 300 ml chicken or vegetable stock
  • 2 lemongrass stalks, bruised and cut into short lengths
  • A thumb-sized piece of galangal or ginger, thinly sliced
  • 4 kaffir lime leaves, torn
  • 1–2 red chillies, sliced
  • 150 g mushrooms (oyster, shiitake or chestnut), sliced
  • 200 g raw king prawns, peeled
  • 1–2 tbsp fish sauce or tamari
  • Juice of 1–2 limes
  • A handful of coriander leaves

Method

  1. Infuse: put the coconut milk, stock, lemongrass, galangal, lime leaves and chilli in a pan. Bring to a gentle simmer and cook for 10 minutes to infuse the flavours.
  2. Add the mushrooms: add the mushrooms and simmer for 3 minutes.
  3. Add the prawns: add the prawns and simmer for 2–3 minutes, until pink and just cooked.
  4. Season: take off the heat and add the fish sauce and lime juice to taste. It should be creamy, sour, salty and a little hot.
  5. Serve: ladle into bowls and scatter with coriander. (The lemongrass, galangal and lime leaves are for flavour and aren't eaten.)

Why it's good for you: Lemongrass, galangal, ginger, lime and chilli are all used in Thai traditional medicine, and together they make a warming, comforting soup that's often eaten during colds. Prawns provide lean protein, selenium and iodine.

Good to know: For a plant-based version, use tofu instead of prawns, vegetable stock and tamari instead of fish sauce.
