Traditional Fermented Buckwheat Injera

1In a large glass or ceramic bowl, whisk the buckwheat flour, 2.5 cups of the filtered water, and the yeast until a smooth, thick paste forms. Cover the bowl tightly with plastic wrap and let it ferment at room temperature (approximately 70°F/21°C) for 48 to 72 hours until the batter becomes sour and develops a liquid layer on top.

2Carefully pour off and discard the dark yellow liquid (ersho) that has settled on top of the batter without stirring the solids underneath; this removes excess bitterness.

3To create the 'absit' (the essential binder), scoop out 1/2 cup of the fermented batter and whisk it with 1/2 cup of boiling water in a small saucepan. Whisk constantly over medium heat for 2-3 minutes until it thickens into a translucent, doughy paste, then remove from heat and let it cool for 5 minutes.

4Whisk the thickened 'absit' back into the main bowl of fermented batter, adding the remaining 1/2 to 1 cup of room temperature water and the salt. Stir until the consistency resembles a thin, pourable crepe batter; it should be thin enough to spread easily but thick enough to hold bubbles.

5Cover the bowl again and let the batter rest for 2 to 3 hours at room temperature until small bubbles begin to form on the surface, indicating the fermentation has reactivated.

6Heat a 12-inch non-stick skillet or a traditional 'mitad' over medium-high heat; if necessary, wipe the surface with a paper towel lightly dipped in oil, then wipe it dry so no visible oil remains.

7Starting from the outside edge of the pan and moving in a continuous spiral toward the center, pour approximately 1/2 cup of batter into the hot pan. Do not swirl the pan like a crepe; the spiral motion creates the traditional texture.

8Immediately cover the pan with a tight-fitting lid to trap steam, which is vital for cooking the top of the bread. Cook for 2 to 3 minutes without flipping; the injera is done when the surface is dry, the 'eyes' (holes) have fully formed, and the edges lift slightly from the pan.

9Use a flat spatula to carefully remove the injera and place it on a clean, cloth-lined surface to cool completely. Do not stack the injera while hot, as they are very moist and will stick together; once cooled, they can be stacked and served.
