Rambutan, scientifically known as Nephelium lappaceum, is a tropical fruit that hails from Southeast Asia. Its name is derived from the Malay word rambut which means hair, a reference to the numerous hairy protrusions covering its skin.
With its luscious, sweet, and juicy flesh, Rambutan is a popular tropical delight enjoyed by many around the world.
Rambutan trees are evergreen, reaching heights of up to 80 feet, and they belong to the Sapindaceae family. The leaves are pinnate, arranged alternately, and are dark green and glossy.
The tree’s canopy provides ample shade, making it a valuable addition to tropical gardens and orchards.
The fruit is small, usually about 3-6 centimeters in diameter, and typically round or oval in shape. It has a distinctive appearance due to its hairy skin, which ranges in color from yellow to red or even orange.
The hairy rind is easy to peel, revealing the translucent and succulent flesh inside. The flesh is similar in texture and taste to lychee, with a sweet and slightly acidic flavor profile. The flavor is often described as a delightful combination of grape and pear, making it a delectable treat.
Rambutan seeds are typically large and inedible, with a shiny appearance. They are usually oval or elliptical in shape and can be easily separated from the flesh. While the seed is not meant for consumption, it is sometimes used in traditional medicine and various local remedies.
