Notes
  • Kaffir lime leaves and lemongrass are common ingredients used in Southeast Asian cookery. They are fibrous and are not for ingestion, but they are very aromatic, adding a refreshing fragrence to the dish. The ginger can also be substituted with galangal, also known as Thai ginger, which imparts an additional aromatic dimension to the soup. All of these ingredients are found at farmers markets and Chinatown markets in Hawai'i.
