Lanzones or langsat (Lansium Domesticum) is an edible tropical fruit native to the Southeastern parts of Asia. Its high content of antioxidants, vitamins, and protein, alongside other minerals, gives it a host of health benefits and medicinal uses.
The fruits of lanzones may be round, oval or elliptical in shape, always appearing in clusters, just like grapes. Having a thin, leathery yellow skin which is easy to peel, the fruits look somewhat like round potatoes. Inside the skin lies the translucent white, juicy fruit divided into five or six sections. The fruit contains 1-3 dark green, inedible, bitter seeds, with no more than one in a single segment.
Its taste may range from tart to sweet, similar to grapes or grapefruit. However, it may be slightly bitter if the seeds remain clung on to the flesh.
Duku is one of the varieties of the Lansium domesticum species, bearing larger and more roundish fruits with a thicker skin. It has a sweeter flavor and unlike the lanzones, do not release any sap on being cooked.
A hybrid between Duku and the Langsat or Lanzones variety is the Duku-Langsat.
Another variation is longkong (also called dokong), introduced in Thailand and Indonesia, having a thick peel, sweet aromatic taste, and no latex. They might contain a few seeds or even be seedless.
