Rambutan (Nephelium Lappaceum) is a very interesting and amazing fruit with a sweet taste, nutrition, and benefits. This fruit is native to southeast Asia. Its appearance seems like a lychee with messy hairs on it.

A friend and family member of Lychee, longan, pulasan and mamoncillo is Rambutan. They all share the same family of Sapindaceae in the family of fruits, Soapberry. The trees of lychee, longan, and Rambutan can go as high as 80 feet. 

 Fun Fact: In the Vietnamese language, they call it chom chom which actually means “Messy hairs”.

The Rambutan fruit is widely cultivated in Southeast Asian areas like Myanmar, Sri Lanka, Malaysia, Indonesia, Thailand, Singapore, and the Philippines.

Appearance

Rambutan trees can go up to heights of 80 feet. The trunk is strong and smooth widened from the bottom. The tree contains small flowers and leaflets sets of 4 to 11.   

Rambutan means ‘hair’ in the Malay language and that’s where the name is derived from. Its numerous hair lumps refer to the origin of the fruit’s name.

Within this hairy protuberance covering is a rose-white tinted, juicy, translucent, sweet with a bit of sour taste flesh. It just has a single seed that is also more or less oblong or ovoid or flattened. 

Taste of Rambutan fruit

The texture of Rambutan fruit seems like lychee but the taste differs as it is a more sweet and creamy texture and has a pinch of sourness in it. The Rambutan fruit has a mildly acidic flavor. If the fruit appears black instead of red or green it is over-ripe.

How to eat Rambutan Fruit?

 The color of the fruit will tell you a lot about the right time to eat it. If the fruit has attained red color then this means it is ripe now and you can pick it for eating. If the fruit goes black and has black hairs it means the fruit is over-ripe to be consumed. 

If you are done with picking the fruit that is ripe and juicy. Just wash it out first and clean it. It is super easy to consume a Rambutan fruit just peel of the outer hairy layer and take out the translucent juicy part and eat it but don’t swallow the seed. 

I have seen three ways people use for peeling off the outer coat of Rambutan fruit. The first ones are those who just peel it off by hand using their fingers to tear the covering. Second, are those who just bite on the hairy coat of rambutan fruit without cringing. And third ones are those who are tidier. They use the knife to cut the coating from the center and take out the fruit just to eat it. (I belong to the third party)
