The santol (also known as wild mangosteen, sandorica) (Sandoricum koetjape) is a tropical fruit grown in southeast Asia.
The santol is believed native to former Indochina and peninsular Malaysia. In the Philippines the santol is widely cultivated and is a popular summer fruit often found in many rural markets. There are two varieties of santol fruit, previously considered two different species, the yellow variety and the red. Both types have a skin that may be a thin peel to a thicker rind. It is edible and contains a milky juice. The pulp may be sweet or sour and contains inedible brown seeds.
Santol preserves are also popular in the Philippines. Boiled and marinated in cane sugar and preservatives, the candied or santol preserve is a popular jam or sweet garnishing for local desserts. (Source: Wikipedia)
