Bohaka injera dough container
A wide-access vessel holds injera batter through successive fermentation stages. Ethiopian accounts describe clay vessels historically and metal, wood or plastic containers in contemporary kitchens.
Traditional method
Injera
A two-stage Ethiopian teff injera method begins with saved ersho, ferments the main batter beneath refreshed surface water, then adds cooked absit before a final warm rest and griddle baking.

The peer-reviewed review identifies injera as a staple Ethiopian fermented flatbread and describes saved ersho, primary fermentation, absit and a second fermentation. This recipe follows a contemporary home recipe for the documented process and does not claim a date of origin.

The teff batter is fermented raw and handled before griddle cooking; CDC warns that raw flour can contain pathogens.
Hazard sourceThe source calls for a covered starter and batter but does not specify a vent; active fermentation produces gas, and closed fermenting containers can build pressure.
Hazard sourceCook each injera fully on the hot griddle before serving and clean hands and surfaces after handling raw flour.
Control sourceDo not seal the fermenting batter in an unvented vessel; use a cover that allows gas to escape.
Control sourceThe recipe does not set a numeric fermentation temperature, acidity endpoint or storage duration. The six-to-seven-day schedule is not a validated safety endpoint.
The recipe source recommends covered fermentation but does not describe gas venting; do not ferment in a sealed, unvented vessel.
Cooked injera should be served; bubbling, sourness and smell do not establish safety.
The recipe source presents injera as a staple in Ethiopia; the review documents the traditional saved-ersho and absit process without claiming a specific city of origin.
