  • 3 small Shallots (Peeled and lightly crushed)
  • 30 g Galangal (Peeled and thinly sliced (young galangal preferred))
  • 3-6 whole Bird's eye chili (Thai chili) (Add whole for aroma, or bruise/chop for spiciness)
  • 1 tsp Salt (To taste, for initial seasoning)
  • 400 ml Coconut milk (unsweetened, canned or carton) (Ready-made, not too thick or thin)
  • 2 tbsp Fish sauce (To taste)
  • 2 whole Lime (Juiced, add to taste)

Instructions

  1. Prepare Chicken

    Debone and remove skin from chicken thighs and/or breast. Cut into bite-sized pieces. If using bones, set aside for broth.

    Time: PT7M

  2. Prep Aromatic Herbs

    Bruise lemongrass stalks with a heavy knife or pestle, then slice. Tear rib from kaffir lime leaves and tear leaves into pieces. Peel and lightly crush shallots. Peel galangal to the white layer and slice thinly.

    Time: PT8M

  3. Start Soup Base

    Bring 1L water to a boil in a medium pot. Add chicken pieces, bones (if using), lemongrass, kaffir lime leaves, shallots, galangal, and whole bird's eye chilies. Add 1 tsp salt.

    Time: PT5M

    Temperature: 100°C

  4. Simmer Soup

    Once soup returns to a boil, reduce heat to medium and simmer for 10-12 minutes, allowing flavors to infuse and chicken to cook through.

    Time: PT12M

    Temperature: 90-95°C

  5. Prepare Fresh Herbs and Lime

    While soup simmers, wash and slice culantro, spring onion, and parsley (or Chinese coriander) into 1 cm pieces. Cut limes as shown: slice off sides and cut stem in triangle shape for easy juicing.

    Time: PT5M

  6. Add Coconut Milk

    Add coconut milk to the pot. Increase heat to bring soup back to a gentle boil.

    Time: PT3M

    Temperature: 100°C

  7. Season Soup

    Taste the soup. Add fish sauce to taste (about 2 tbsp). Taste again; soup should be slightly saltier than desired, as lime juice will balance it.

    Time: PT2M

  8. Finish with Herbs and Lime

    Once soup boils again, add sliced culantro, spring onion, and parsley. Remove pot from heat. Squeeze in lime juice to taste (start with juice of 1 lime, add more as needed).

    Time: PT3M

  9. Adjust Spiciness and Serve

    Add bruised or chopped bird's eye chili for desired spiciness. Serve hot.

    Time: PT2M

  10. Cleanup

    Wash all utensils, cutting board, knife, pot, and bowls. Wipe down kitchen surfaces.

    Time: PT15M
