A reference entry establishing the identity and culinary role of the principal Thai herbs — not a preparation but the knowledge layer that underpins every Thai preparation. Thompson's books are built on the assumption that the cook understands the difference between the Thai herbs and their uses; the Provenance ingredient intelligence layer should surface this knowledge at the point of recipe engagement. Each herb is listed with its Thai name, the flavour compounds responsible for its character, when it is added in a preparation, and what it cannot be substituted with.
