Things You Need to Know About the Rambutan Fruit
Rambutan is a tropical fruit that is native to some regions of Southeast Asia. This Buzzle write-up provides information about the flavor, nutritional value, and health benefits of the rambutan fruit.
Refrain from buying rambutans that are green or black in color. The green color suggests that the fruit is not ripe, whereas, the fruits that have a black-colored rind are most likely to be overripe.
Native to Malaysia and Indonesia, rambutan is a tropical tree that belongs to the Sapindales order and Nephelium genus. Its scientific name is Nephelium lappaceum. The tree bears juicy fruits that are also called rambutans. The rind of this fruit is mostly red in color, but you may come across varieties that have a yellow or orange-colored rind. In Malay, the term 'rambut' means hair. The fruit gets its name from the 'hair-like bristles' that are present on its exterior. Under its distinctive, spiky rind lies sweet, edible flesh. So, to eat a rambutan, all you need to do is remove the rind. Under the flesh lies its seed, which is not edible. So, make sure that you discard the seed.
Studies conducted by a group of scientists from the Aklan State University, Philippines, revealed that the application of a plant growth regulator called Gibberellic acid (GA3) could help inhibit the development of seeds. Though these seedless fruits might have the same weight and diameter as the rambutans with seeds, they are not as long.

What Does the Rambutan Fruit Taste Like?
Differences Between Rambutans and Lychees
If not for the spines or bristles, this fruit would look very similar to a lychee, another tropical fruit. Lychees don't have bristles on the rind, but their rind is rough to touch. Lychee fruits have a thin rind, in comparison to rambutans.
How to Eat the Rambutan Fruit
In order to eat this fruit, you will need to remove the outer covering. To remove its peel, make a shallow cut on its exterior using a knife. Apply a little bit of pressure along that cut, so as to expose the white flesh. Thereafter, remove the peel. You will find an oval-shaped, 2 to 3-inch long white aril that is wrapped around the seed. Ripe rambutans easily slip out of the soft spiny skin (pericarp). In some varieties, the flesh is tightly bound to the seed (clingstone). In some varieties, the flesh easily slips away from the seed (freestone). Surely, once you get a taste of the juicy sweetness, you will agree that it was totally worth the effort.
