Description
Tubers are boiled, soaked in ash‑water, and buried in ash to preserve them for months.
Technical
The high pH (9–10) created by ash‑water denatures spoilage enzymes and inhibits bacterial growth. Ash provides calcium, potassium, and sodium carbonates that act as mild preservatives and mineral supplements, while the alkaline environment leaches sugars and reduces glycoalkaloid content.
