Iru, or fermented locust bean, is a popular condiment in West African cooking. Rich in protein and fats, it imparts a deep umami flavor to savory and sweet dishes. The complex flavor is somewhere in between chocolate, miso, and cheese. This ingredient goes by a variety of names depending on the region, but the Yoruba people of Nigeria call it Iru, and it has been used for centuries across West Africa for its delicious and healthful properties. Today, it's at risk of disappearing from kitchens, and we want to make sure you get to know this beautiful spice, which is perfect for umami-rich stews, sauces and bean dishes. Despite its wide applications across West African cuisine, it's still surprisingly difficult to find in the US, especially in dry bean form.
