Fermented sweet potato mash is a lactic‑acid fermented product of gelatinized sweet potato starches.
Origin: Cherokee, Navajo, Eastern Woodlands peoples (Traditional Indigenous practices) — Eastern Woodlands, North America
See full technique reference →During fermentation, lactic acid bacteria such as Lactobacillus plantarum convert gelatinized starches into lactic acid and small amounts of ethanol, while endogenous amylases break down starch into fermentable sugars. The process also generates volatile compounds like acetaldehyde and diacetyl, which contribute buttery and nutty notes to the flavor profile.
Primary Reaction
Starch → lactic acid + ethanol (lactic acid fermentation)
