What is Rambutan – A guide to Chom Chom fruit of Vietnam


Rambutan, or “Chom Chom” fruit in Vietnamese, is a tropical fruit native to Southeast Asia. Rambutan gets its name from the Malay word for hair, as the fruit has fur-like hair growing from its head. When ripe, rambutan has an eye-catching red color and the edible flesh is lightly sweet with many nutrients. In this article, let’s explore rambutan, the benefits of rambutan and the fruit juice drink from rambutan.

What is rambutan

Origin of Rambutan

Rambutan (Nephelium lappaceum) is a tropical fruit that belongs to the Sapindaceae family, which also includes lychee and longan native to Southeast Asian. The name “rambutan” comes from the Malay word “rambut,” which means “hair,” and it is aptly named due to the hairy or spiky appearance of the fruit’s skin.

The rambutan fruit is round or oval in shape and its size same as table tennis. The rambutan’s outer skin is covered with soft, flexible spines or hairs that turn from green to yellow or red as the fruit ripens. The fleshy interior of the rambutan is translucent, juicy, and sweet, with a mildly acidic flavor. The single seed is large and usually adheres to the flesh.

Rambutans are commonly eaten fresh, but they can also be used in salads, desserts, and beverages. The fruit is rich in vitamin C, fiber, and various antioxidants. Rambutan trees thrive in warm, tropical climates, and they are cultivated in countries such as Vietnam, Thailand, Indonesia, Malaysia, the Philippines, and other parts of Southeast Asia.


Rambutan taste

Rambutan has a delicious and unique flavor that is both sweet and mildly acidic. The taste can be described as a perfect blend of sweetness with a slightly tart undertone, creating a refreshing and tropical experience. The juicy and translucent flesh has a texture similar to grapes but is distinct in its own right.

The sweetness of rambutan is often compared to that of grapes or lychee, but its flavor profile has its own nuances. Some varieties of rambutan may have subtle variations in taste, with some being exceptionally sweet and others having a touch more acidity.

The difference between: Rambutan vs Lychee vs Longan

Rambutan, lychee, and longan are all tropical fruits of the Sapindaceae family. They have some similarities in nutritional composition but their appearance and taste are quite different:

rambutan vs lychee vs longan

Rambutan (Nephelium lappaceum)

Rambutan is a round or oval fruit with a soft, pointed outer shell that changes from green to yellow or red when ripe. The taste of rambutan is sweet and slightly sour, the flesh is clear, succulent, and has a texture similar to grapes. Rambutan fruit flesh tends to stick to the seeds more tightly than lychees and longans. Rambutan is usually the largest size of these three fruits, sometimes they are the size of a lychee, but the outer layer of hair makes rambutan very different.

Lychee (Litchi chinensis)

Appearance: The Lychee has a rough outer shell, usually pink or red. When peeled, the fruit will reveal transparent, succulent flesh with a strong aroma. The size of the lychee is a little smaller than a ping pong ball, and the flesh is easier to separate from the seeds than rambutan. Lychee has a sweet and floral flavor with a hint of sourness. The texture is juicy and crispy.

Longan (Dimocarpus longan)

Longan has the smallest fruit size and is round in shape. The outer shell is smooth, golden brown to light brown. When peeled, it reveals a translucent grape-like fruit with a seed in the middle. Longan has a pure sweet taste, without any sour taste. The fruit’s flesh is succulent and has no seeds attached, like lychee.

Although these fruits have similarities, their distinct flavors and textures make each a unique tropical treat. Some people may like the sweet and slightly sour taste of rambutan, the delicate sweetness of lychee or the mild sweetness of longan.
