Description
Kisra is a traditional Sudanese fermented sorghum dough that is allowed to rise at ambient temperatures for 12–24 h, producing a slightly sour, airy bread cooked on a hot griddle.
Technical
During fermentation, lactic acid bacteria convert sorghum starches into lactic acid, lowering the pH to 4.5–5.0 and creating a mildly acidic environment that preserves the dough. Yeasts simultaneously metabolize sugars to produce CO₂, which expands the dough and imparts a characteristic airy texture. The combined metabolic activities also generate trace alcohols and flavor compounds that contribute to the bread’s subtle sweetness and yeasty aroma.
