Prep Time: 15 mins
Total Time: 45 mins
  1. 1 Cut the lemongrass into 5 cm pieces and pound the pieces with the side of your kitchen knife to bruise them. This helps to release the flavour into the soup.
  2. 2 Using a large saucepan- combine the stock, lemongrass pieces, galangal, whole lime leaves and coriander (cilantro) roots and stems mixture. Bring to the boil. Reduce the heat. Simmer covered for 5 minutes.
  3. 3 Remove from the heat and allow to stand for 10 minutes.
  4. 4 Strain the stock through muslin or a fine strainer into a large heatproof bowl. Discard the solids.
  5. 5 Rinse your saucepan.
  6. 6 Return your stock/soup base to the same saucepan.
  7. 7 Add chicken and straw mushrooms. Bring to the boil. Reduce heat and simmer uncovered for 5 minutes, or until the chicken is cooked through.
  8. 8 Stir in the coconut milk, lime juice, fish sauce and the sugar. Cook, stirring, until only just heated through. Do not boil. Remove from heat.
  9. 9 Add the remaining ingredients- coriander (cilantro) leaves, red chillies, kaffir lime leaves and the lemon grass slices.
