What You Need to Know
Repeated impact forces from wooden pestles (typically iroko or odum wood) cause localized starch gelatinization through frictional heating (45-60°C). Concurrently, amylopectin chains align into pseudo-crystalline structures stabilized by hydrogen bonding with residual moisture (30-40% water content).
Transforms dense, fibrous tubers into a smooth dough with unique stretchability ideal for scooping soups and stews.
