African Sun ground ogbono to add thickness to ogbono soup. Ogbono seeds (also known as wild mango or African mango) are mango-like fruits. Once ground, they can be used as a thickener and provide a dark colour to soups. Hearty ogbono soup is a mixture of meat (chicken, goat, beef), fish (shrimp or crayfish), leafy vegetables and palm oil, which is served with fufu, a West African starchy side made from ground plantains, cassava or yams.
