IRU (also known as OGIRI) is a traditional West African seasoning made from fermented locust beans, prized for its pungent, umami-rich flavor profile. This ingredient delivers deep, savory complexity to soups, stews, and sauces, particularly in Nigerian and Ghanaian cuisines. The fermentation process concentrates natural glutamates, creating an authentic taste that elevates classic dishes like egusi soup and pepper soups. A small amount goes a long way, making it an economical pantry staple for home cooks seeking genuine African flavors. Store in a cool, dry place to preserve its potent aroma and distinctive character.
