Ogiri is a traditional fermented seasoning originating from southeastern Nigeria, particularly among the Igbo people. It is typically produced from fermented oil-rich seeds, including castor seeds (ogiri-igbo) and melon seeds. Ogiri has a strong, pungent aroma and a distinctive savoury flavour. It is commonly used as a flavour enhancer in traditional Nigerian soups and dishes, including oha, bitterleaf, egusi and nsala soup.


Ogiri is traditionally made from the fermentation of egusi (melon seeds), although there are other types of Ogiri made from different seed substrates, such as sesame, castor oil beans (Ogiri Igbo), fluted pumpkin seeds, watermelon seeds, and peanuts, all produced at lower frequencies.: p. 4
