Teff or taf Â is an annual grass, a species of lovegrass native to the northern Ethiopian Highlands of northeastern Africa. It has an attractive nutrition profile, being high in dietary fiber and iron and providing protein and calcium. It has a sour taste. It is similar to millet and quinoa in cooking, but the seed is much smaller. Teff is an important food grain in Ethiopia and Eritrea, where it is used to make injera, and less so in India and Australia. (It is now raised in the USA, in Idaho in particular.) Because of its small seeds (less than 1 mm diameter), one can hold enough to sow a large area in one hand. This property makes teff particularly suited to a seminomadic lifestyle. Common names include teff, lovegrass, annual bunch grass (English).
