Guittiferae is the genus

the most delicious fruits, along with a tree that ranks very high among the most beautiful flowering trees of the world.   A few of the trees in the family do have seeds that are rich in edible oil.

Bitter Kola
False Kola

These are related to the mangosteen family.   The 400 kinds of garcinia in Asia and South Africa include the mangosteen, one of the world's most delicious fruits. 

The seeds are found in markets in Senegal and other African countries.   The seeds have a bitter, astringent, resinous taste somewhat resembling that of raw coffee beans but in the form of chewing gum.   After chewing a few minutes, the taste turns sweeter and is a substitute for the Kola Nut.  Chewing the seeds enhances the flavor of the native liquor.

Only ripe fruits should be used for extraction.  The nuts are often used as a substitute for KOLA NUTS.  When the seeds are young, they are edible.

KOKAM BUTTER is made in India from the FALSE KOLA.  The seeds kernels are pounded, water added to the pulp, and it soaks overnight.  During the night the oil rises to the surface and forms a white layer which is removed in the morning.  The mixture is then churned, and the oil, like butter, rises to the surface in a solid form and is removed by hand.   Kokam Butter is found in the bazaars of India.  it consists of cakes of a yellowish color and has a "greasy" feel.   When fresh it also has a faint, and pleasant, smell   The butter is used mostly to make soap, but the butter is also used to add to "ghee" or "butter".
