The Serumpun Codex
Forty Sarawak ingredients, each with the community whose knowledge it carries.
The Codex is Serumpun's record of the Sarawak larder. Every entry gives the same fields in the same order: the community's own name for the ingredient, whose knowledge it carries, how they use it, and how we cook with it. Where a fact is not yet confirmed, the entry says so rather than guess.
How the Codex is kept
Consent comes first. For every entry, the communities gave it through CHASS, the Culinary Heritage and Arts Society Sarawak, on 30 October 2026, under Serumpun's ten principles. Anyone may cook from an entry, commercially too, provided the community is credited by name. Medicinal knowledge stays with the communities. A community can correct or withdraw its entry at any time.
Some entries carry a historical botanical or natural-history plate, now in the public domain, with its artist, book and year. The plate shows the plant. The knowledge belongs to the community named in the entry.
Every fact carries its source. Where an ingredient falls under a Codex Alimentarius standard or a Malaysian Geographical Indication, the entry gives it.

Questions answered
What is the Serumpun Codex?
A public record of forty Sarawak ingredients kept by Serumpun Sarawak. Each entry names the ingredient in its community's own word, credits the community whose knowledge it carries, and sets out how it is used and how Serumpun cooks with it, with the sources for every fact.
Can I cook from the Codex?
Yes, commercially too, provided the community an entry comes from is credited by name. This is principle four of Serumpun's principles.
Who gave consent for the entries?
The communities, through CHASS, the Culinary Heritage and Arts Society Sarawak, recorded on 30 October 2026. No entry is published without it.
Why are some fields marked to be confirmed?
Because no source yet confirms them. Each entry names those fields in one line, until a community, a specimen or a published source settles them.
Why is medicinal knowledge not published?
Medicinal uses shared with Serumpun stay with the communities unless they choose otherwise. Every entry marks that field as held privately.
How can a community correct or withdraw an entry?
By writing to the Custodian at connect@chefjameswon.com. A withdrawal is completed within ninety working days.
