Egusi
Egusi (Yoruba) (also known as agusi, ohue, Ikpan, Ikon, agushi or mbíka) is the name for the protein-rich seeds of certain cucurbitaceous plants (squash, melon, gourd), which, after being dried and ground, are used as a major ingredient in West African cuisine.
In Igbo, among whom it is very popularly eaten, it is often called egwus(h)i.
Egusi melon seeds are large and white in appearance; sometimes they look brownish or off-white in color but the main egusi color is primarily white.
Scholars disagree whether the word is used more properly for the seeds of the colocynth, those of a particular large-seeded variety of the watermelon, or generically for those of any cucurbitaceous plant. Egusi seeds are in a class of their own and should never be mistaken for pumpkin or watermelon seeds. In particular the name "egusi" may refer to either or both plants (or more generically to other cucurbits) in their capacity as seed crops, or to a soup made from these seeds and popular in West Africa.
The characteristics and uses of all these seeds are broadly similar. Major egusi-growing nations include Nigeria, Burkina Faso, Togo, Ghana, Côte d'Ivoire, Benin, Mali, and Cameroon.
Species from which egusi is derived include Melothria sphaerocarpa (syn. Cucumeropsis mannii) and Citrullus lanatus.
