Injera

Method

1. mix10 min
   room temperature
   teff flour + 3 cups water, whisked until no dry pockets remain and the slurry pours like thin cream — teff is tiny and mostly bran, and the wild yeast and lactic bacteria that will sour this live on that bran, so unwashed flour and an unsterilized bowl are features. Add ersho now if you have it; it only speeds a ferment that would happen anyway.
2. ferment4320 min
   22-26°C, covered with cloth, not sealed
   Three days. The batter separates: a layer of dark, sharp-smelling liquid rises above the settled flour every day, and you pour it off and discard it each morning. That liquid is where excess acetic acid and the bitter breakdown products collect — leave it in and the injera turns puckering and metallic instead of cleanly sour. A sealed lid traps CO2 and pushes the culture toward the sour-beer end of the spectrum; cloth lets it breathe. By day three the surface should be domed with fine bubbles and smell like yogurt, not like solvent.
3. boil8 min
   medium, whisking constantly
   1 cup boiling water + about half a cup of the fermented batter, whisked until it thickens to a loose paste = absit. Cook it a full minute past thickening so the starch granules truly swell and burst. Cool it to lukewarm before it goes back in — poured in hot it kills the culture you spent three days building.
4. rest120 min
   covered, warm
   absit stirred back into the main batter + enough water to bring it to the thickness of heavy cream. The gelatinized starch traps the gas the yeast is still making, which is the whole reason the eyes hold their shape instead of collapsing the instant they open. The batter should be visibly puffed and foamy on top before you pour.
5. season1 min
   + salt, folded in at the last moment. Salt from the start would have throttled the lactic bacteria and you would be on day six with a batter that never soured.
6. saute16 min
   dry or barely oiled pan, medium-high, lid on
   Pour about three-quarters of a cup in a spiral from the outer rim inward, in one unbroken motion — stop and restart and the seam sets as a ridge. Within thirty seconds the surface should erupt in small craters, the eyes; if it stays smooth the pan is too cool or the batter over-thinned. Cover and steam 2 minutes until the top is matte and dry all the way to the center. Never flip it: injera cooks from one side only, and the spongy top face is the side that has to stay soft to pick up stew. Repeat for four sheets, letting the pan recover between pours.
7. rest15 min
   on cloth, single layer then stacked
   Lift each sheet onto a cloth and let it cool flat before stacking. Peeled and folded hot, the gelatinized starch is still weak and the sheet tears down the middle; cooled, it turns leathery and pliable and will roll without cracking.
