PRACTICAL WALKTHROUGH · PARAMETERS · COMMON MISTAKES
A low‑energy method of preserving wild berries by sun‑drying them on woven mats.
Origin: Indigenous American groups (Navajo, Pueblo, Maya, Inca, etc.) (pre‑Columbian) — North and South America
See full technique reference →During drying, water molecules are removed from berry tissues by evaporation, lowering moisture content and water activity. The reduced water activity (<0.6) inhibits microbial growth while concentrating sugars, phenolics, and volatile aromatics that contribute to flavor. The process is driven by ambient temperature (20–30 °C) and airflow through the woven fibers, which also prevents ground contamination.
