Known as Iru by the Yorubas and Daddawa by the Hausas (and often misspelt and mispronounced by others as “dawadawa”), it is similar in taste and smell to Thai fish sauce (savoury, salty and pungent). Sold as loose seeds (iru) or small flat, dark patties (daddawa).

Medical benefits are said to include:  control of blood pressure, blood sugar and bad cholesterol; and treatment of stomach and mouth ulcers. 
Store in sealed containers in the freezer.
