MAKES 18 FLATBREADS
Injera, the spongy, crêpe-like sourdough flatbread usually made from tef, a hardy Ethiopian grain, can be easily replicated at home with all-purpose flour, yeast, and a nonstick skillet. (See Making an Ethiopian Staple, for the traditional method.)
1 cup warm water (about 105°)
1 1⁄4-oz. packet of active dry yeast
3 cups flour
1⁄2 tsp. kosher salt
1. Pour warm water into a small bowl, sprinkle with yeast, and let stand until foamy, about 10 minutes.
2. Sift flour into a large bowl; add the yeast mixture along with 2 cups water and whisk until a very smooth batter has formed. Cover tightly with plastic wrap and let sit at room temperature for 4 hours.
3. Briskly whisk the bubbling batter until smooth; add salt and whisk to combine.
4. Heat a 6" nonstick skillet over medium-low heat. Pour in 1⁄4 cup of the batter, tilting and swirling the skillet to coat it evenly with batter. Cook until just set, about 1 minute. Cover and cook until the edges pull away slightly from the sides, about 1 minute more. Using a heatproof rubber spatula, transfer injera to a paper towel–lined plate, cover with another paper towel, and repeat, stacking the flatbreads as you go. (Whisk the batter while each flatbread cooks.)
5. Let injera cool completely; wrap with plastic wrap until ready to serve. (The injera may be stored overnight in the refrigerator; bring to room temperature before serving.)
