Frequently Asked Questions

Q

How much teff flour per injera?

A 12-inch traditional injera uses about 65g of flour. For 100% teff, that means 65g teff flour and 95ml water per flatbread. The batter should be thin like crepe batter. One cup of teff flour (120g) makes roughly 2 full-sized injera.

  • 12-inch injera: 65g flour + 95ml water per flatbread
  • 10-inch medium: 45g flour + 65ml water
  • 8-inch small: 30g flour + 45ml water
  • 1 cup teff flour (120g) ≈ 2 full-sized injera
  • Batter consistency: thin like crepe batter, not pancake

Q

How long does injera batter need to ferment?

Injera batter ferments for 2–3 days at room temperature (72–78°F). The natural wild yeast in teff creates the characteristic sour flavor and bubbly texture. Bubbles on the surface indicate fermentation is active. A sour smell similar to sourdough is normal and desired.

  • Fermentation time: 2–3 days at room temperature
  • Ideal temperature: 72–78°F (22–25°C)
  • Signs of readiness: bubbles on surface, sour smell
  • Warmer climates: may be ready in 1.5–2 days
  • Colder climates: may need 3–4 days
Q

Can I use a mix of teff and regular flour?

Yes, many home cooks blend teff with all-purpose flour. Common ratios are 75% teff / 25% AP flour (closer to authentic) or 50/50 (more accessible flavor). Pure 100% teff gives the most authentic flavor and characteristic dark color but costs more and can be harder to work with.

  • 100% teff: most authentic, dark color, strongest sour flavor
  • 75/25 teff/AP: good compromise, still distinctly Ethiopian
  • 50/50 blend: lighter color, milder flavor, easier for beginners
  • White teff vs brown teff: white is milder, brown is earthier
  • Cost: 100% teff is $5–8/lb vs $1–2/lb for AP flour
Q

How many injera per person for an Ethiopian meal?

Plan 2 full-sized (12-inch) injera per person: 1 as a base plate for the stews and 1 for tearing and eating. For a large communal platter, use 1 large injera as the base and have 1.5 extra per person on the side.

  • Per person: 2 full-sized (12-inch) injera
  • Base plate: 1 injera laid flat with stews on top
  • Eating bread: 1 injera cut into triangles for scooping
  • For 4 guests: make 8 injera total
  • Leftover injera keeps 2 days in plastic wrap at room temp
