Step 1

In a large mixing bowl, combine teff flour, all purpose flour, instant yeast, salt and baking soda. Mix well. Stir in apple cider vinegar and warm water. Whisk vigorously into a smooth batter without lumps. Cover and set aside for 1 hour in a warm spot.

Step 2

Preheat a 9" non-stick or cast-iron skillet on high heat for 5 minutes. Lightly spray the skillet with cooking spray. Pour ¼ cup of the batter on the outside of the hot pan and work in a spiral toward the center. Tilt the pan to fill in any holes. Immediately cover the pan with a loose-fitting lid and let the injera cook for 2~3 minutes.

Step 3

Injera is done when the top is no longer shiny or wet and feels firm to touch. Transfer the cooked injera to a plate and cover immediately with a kitchen towel or a plastic wrap. Repeat with the remaining batter.Stack the injera on top of each other. Keep them covered to keep them moist and soft.
