Ingredient

Teff

Teff is the smallest cultivated grain in the world — a single seed is about the size of a poppy seed — and it is the staple of Ethiopia and Eritrea, where it is fermented and cooked into injera, the vast spongy flatbread that serves as plate, bread and utensil at the same time.

What it is, and why the size matters

Teff is a cereal grass grown mainly in the Ethiopian highlands. Its seeds are so small — thousands to a gram — that they cannot practically be separated into bran, germ and endosperm the way wheat or rice can.

That has a real consequence: teff is always a wholegrain flour. There is no white teff flour in the sense that there is white wheat flour, because milling the germ and bran out of something that small is not feasible. Whatever you buy contains the entire seed.

The size also makes it very quick to cook as a whole grain, and it makes teff flour behave differently from other flours — fine, absorbent and quick to hydrate.

It contains no gluten, which matters for injera: the structure of that bread comes from fermentation gas trapped in a starch batter rather than from a gluten network.

The varieties, and what they taste like

Brown or red teff

The most common. Earthy, nutty, faintly molasses-like, with a distinct mineral note. Darker injera.

Ivory or white teff

Milder and more delicate, slightly sweeter. Prized in Ethiopia and generally more expensive. Paler injera.

Whole grain

Cooks in around fifteen to twenty minutes into a texture somewhere between couscous and porridge — the grains stay distinct but the starch thickens the whole thing.

Flour

Very fine and highly absorbent. Absorbs more liquid than wheat flour and produces dense, moist results.

Injera, and what makes it work

Teff flour is mixed with water into a thin batter and left to ferment for several days with a starter (ersho) from a previous batch. Wild yeasts and lactic acid bacteria go to work, and the batter becomes sour and full of gas.

It is then poured in a spiral onto a large flat griddle — the mitad — and covered. It cooks on one side only. As the gas escapes it leaves the surface covered in small holes, the injera "eyes", which are the mark of a properly fermented batter. The finished bread is soft, flexible, faintly spongy and distinctly sour.

At a meal, injera is spread across a communal platter, the stews and vegetables are ladled on top, and more injera is served rolled at the side. You tear off a piece and use it to pick up the food. The bread underneath soaks up the sauces and is eaten last, and it is the best part.

Many restaurant and home versions outside Ethiopia mix teff with wheat or barley flour, partly for cost and partly because a pure teff injera is genuinely difficult to get right.

Cooking with teff outside injera

• As a porridge, cooked in water or milk. Nutty and quick, and it thickens considerably more than oats.
• As a side grain, cooked like a fine couscous and used under stews.
• In baking, substituted for up to about a quarter of the wheat flour in bread, pancakes, muffins or biscuits. It adds a nutty, malty depth and a darker colour.
• In gluten-free baking, as part of a flour blend rather than alone — it is absorbent and needs balancing with a lighter starch.
• In pancakes and crumpets, where its slight sourness and fine texture suit the format.
• Toasted before cooking, in a dry pan for a couple of minutes, which deepens the nuttiness noticeably.
• Not as a direct one-for-one wheat replacement. It absorbs more liquid and provides no gluten, so a recipe needs adjusting rather than swapping.
