What You Need to Know
During fermentation, lactic‑acid bacteria metabolize sorghum sugars, producing lactic acid that lowers the dough pH to ~4.0. The acid partially gelatinizes starch granules, increasing viscosity and creating a porous crumb. Rapid surface heating on a hot griddle denatures sorghum proteins and sets the starch matrix, yielding a thin, flexible flatbread.
