Infuse the Broth

2
  • Strain out or leave in the lemongrass and galangal (traditionally, they’re left in but not eaten).

  • Add chicken slices and mushrooms to the pot.

  • Simmer gently for 7–10 minutes, or until the chicken is just cooked and mushrooms are tender.

Season & Finish

  • Stir in fish sauce, sugar, and lime juice. Adjust to taste — balance should be creamy, tangy, salty, and lightly sweet.

  • Remove from heat.

Garnish & Serve
