Eba
Ẹbà is a Nigerian staple food eaten in West African subregion and beyond. It is made from dried grated cassava (manioc) flour, commonly known as garri.
To make ẹbà, gari flour (which should be further pounded or ground if not already 'fine') is mixed into hot water and stirred well with a large wooden spoon until it becomes like a firm dough, firmer than, say, mashed potatoes, so it can be rolled into a ball and can keep its shape.
To eat, a small amount of ẹbà is taken with the fingers and rolled into a small ball and dipped into the ọbẹ (a thick soup) such as okra soup, bitter leaf (ewurò) soup or pepper soup (ọbẹ ata or efo depending on dialect) with either okro, ọgbọnọ (Igbo)/apọn (Yorùbá), or ewédú, meat or fish, stewed vegetables or other sauces such as gbegiri, banga soup or egusi soup (melon).
