Can I make injera without a clay mitad?

Yes — a wide, heavy, flat pan with a tight lid is the standard home substitute. Heat it fully, pour the batter in a spiral, cover for 1-2 minutes and do not flip: the lid traps the steam that sets the top surface.

My kitchen is colder than 20 °C. How long will the batter take?

Plan on 5 days or more. Below 15 °C fermentation slows sharply, so move the bowl to the warmest spot you have — near a radiator or in an oven with only the light on — and judge readiness by sour smell and pH 4.0-4.5, not by the calendar.

How do I know when the batter is ready to bake?

By smell and acidity, not by hours. A ready batter smells clearly sour and measures pH 4.0-4.5; at 20-25 °C that usually takes 48-72 hours, or 24-48 hours with a cup of ersho starter stirred in.

How long does teff flour keep before it goes off?

Whole grain keeps 6-12 months sealed in a cool, dry place; stone-ground flour is best within 3-6 months. The germ oil in whole-milled flour turns rancid, and rancid flour carries the off-flavour straight into the bread.

Injera for six at home

Massiwa Market — An Eritrean and Horn-of-Africa | massiwa-market.com

To feed six people injera at home you need 600-900 g of teff flour, roughly 0.9-1.6 litres of water, two to three days of fermentation at 20-25 °C and a wide lidded pan to stand in for a clay mitad. This page lays out the batch maths, the flour grades, the timing and the equipment, in working order.

The batch at a glance

1.5 mmsize of one teff grainAbout poppy-seed size, milled whole with bran and germ, so the flour is naturally gluten-free.

2.5-2.7 kgbatter from 1 kg of flourMixed with 1.5-1.8 litres of water, one kilogram of flour is enough for 12-16 injera of 40 cm.

150-250 mlersho starter kept backA cup reserved from the previous batch shortens the next fermentation to 24-48 hours.

What you need for six people, in one list

Flour, water, time and a lidded pan — the whole kit fits in a paragraph.

The core buy is teff flour: 600-900 g covers six adults at 100-150 g per person per meal. A standard 1 kg retail bag is therefore the natural unit for a six-person dinner, with a margin left over to seed the next starter.

Water goes in at 1.5-1.8 litres per kilogram of flour, so for six people that is roughly 0.9-1.6 litres. Mixed, you get about 1.5-2.5 kg of batter, which pours out as 8-14 large injera of 40 cm — one to two per guest.

Everything else is time and heat. The batter needs 48-72 hours at 20-25 °C to turn sour, and each injera needs 1-2 minutes on a hot covered surface. No flipping, no oven, no ingredients beyond flour and water.

Terms used on this page

Teff: A tiny grain about 1.5 mm across, roughly poppy-seed size. It is milled whole — bran, germ and all — so teff flour is naturally gluten-free.
Injera: A large sour flatbread, typically 40 cm across, poured in a spiral from fermented teff batter and cooked covered without flipping.
Ersho: The starter kept back from a finished batch, about 150-250 ml. Stirred into the next mix, it shortens fermentation to 24-48 hours.
Mitad: The clay griddle, 40-60 cm wide, on which injera is baked. A heavy flat pan with a tight lid is the usual home substitute.
Berbere: The chilli-led spice blend of the Horn of Africa, typically 10-15 ingredients with ground chilli at 40-60% of the weight.
Stone-ground flour: Teff milled whole between stones. Because the germ oil stays in, it is best used within 3-6 months before it turns rancid.

How this reference is put together

Every figure on this page comes from standard product and preparation data for teff and injera: grain size, pack sizes, hydration ratios, fermentation temperatures and cooking times. Where a range exists, both ends are shown rather than a single average. No prices, suppliers or brands are listed, because this page is a reference, not a shop.

Where the numbers come from

The figures reflect commonly published specifications for teff grain, injera batter and berbere blends, with ranges quoted wherever those specifications differ.
