The Māori method sun‑drying kūmara with a salt crust preserves the sweet potato by lowering water activity and creating an anaerobic barrier.
Origin: Māori (Traditional (pre‑colonial to early 20th century)) — New Zealand
See full technique reference →Salt draws water out of the slices, reducing water activity below 0.6 and inhibiting mesophilic bacteria. The crust also limits oxygen exposure, slowing starch oxidation and preserving vitamin C. Controlled temperature and humidity ensure sufficient moisture loss without mold growth.
