PRACTICAL WALKTHROUGH · PARAMETERS · COMMON MISTAKES
Acorn paste is produced by leaching acorn kernels to remove tannins and then cooking the resulting paste to gelatinize starch.
Origin: Miwok, Pomo, Yurok, Hupa tribes (pre-colonial) — California, USA
See full technique reference →The leaching step relies on the solubility of hydrolyzable tannins in water; repeated water changes and a rising pH reduce tannic acid to below 0.1% of the meal. Subsequent heating near boiling causes starch granules to swell and gelatinize, forming a cohesive dough that can be dried or shaped.
