Fermented Condiments & Pastes

Iru / Dawadawa / Ogiri

West African fermented seed condiments — locust bean, sesame, or castor seed — that deliver deep, pungent umami in soups, stews, and sauces.

Definition

Iru, dawadawa, and ogiri are a family of fermented condiments indispensable to West African cooking, each made from different seeds but sharing the same purpose: providing a concentrated, funky, savory depth analogous to miso or fish sauce in other traditions. **Iru** (Yoruba, Nigeria) is made from the seeds of the African locust bean tree (*Parkia biglobosa*). The seeds are boiled to remove the pulp, then fermented in sealed pots for three to four days, developing a pungent, ammonia-edged aroma and a sticky, brown paste. Iru is used fresh or dried into nuggets; fresh iru is more potent. It seasons egusi soup, efo riro, gbegiri (bean soup), and jollof rice bases. **Dawadawa** is the Hausa name for the same locust bean ferment, widely used across the Sahel — Nigeria's north, Mali, Senegal, Burkina Faso, and Ghana. It is usually pressed into balls or discs and dried, giving it a longer shelf life. The Senegalese and Malian versions are often called *sumbala* or *netetou*. **Ogiri** (Igbo, Nigeria) differs from iru in substrate: it is fermented castor seeds (*Ricinus communis*, dehulled and detoxified through extended fermentation) or sometimes melon/egusi seeds. Its smell is sharper and more sulfurous than iru, but the flavor contribution to soups like ofe onugbu (bitter leaf soup) and ofe akwu (palm nut soup) is profound. All three condiments work through alkaline fermentation driven by *Bacillus subtilis* and related bacteria, which break down proteins into free amino acids, producing glutamate-rich paste. The funky aroma compounds (pyrazines, short-chain fatty acids) soften significantly with cooking, leaving an umami backbone rather than raw pungency. Cooks use them in small quantities — a teaspoon of iru or a marble-sized piece of ogiri — as one would use a bouillon cube, but with far more complexity.

In use

“She pounded a small piece of dried dawadawa into the groundnut soup base, releasing a wave of savory funk that anchored the entire pot.”

Notes

Buying and Storing

Fresh iru is sold in West African grocery markets wrapped in leaves; its shelf life at room temperature is only a few days. Dried dawadawa balls keep for months in an airtight jar. Ogiri in the West is most often found vacuum-sealed or frozen. The smell on opening is alarming; this is normal and dissipates in the pot.

Substitution

No single substitute fully replicates the locust-bean funk, but a combination of a small amount of doenjang (Korean fermented soybean paste) with a few drops of fish sauce comes closest in umami depth. Miso alone is too mild and too sweet.
