Nam pla (fish sauce) is the foundational seasoning of Thai cooking — not a flavour addition but the structural salt of the cuisine, replacing table salt in virtually every application. The specific amino acid and nucleotide profile of Thai fish sauce (made primarily from anchovies — pla raa — fermented with salt at 3:1 fish-to-salt ratio for 12–18 months) produces a umami depth that salt alone cannot provide.
