17 Interesting Facts About Pulasan

Pulasan (Nephelium mutabile) is a tropical fruit related to the rambutan and lychee, native to Southeast Asia, particularly Malaysia and Indonesia. The fruit is known for its vibrant appearance, with a thick, spiny, or bumpy skin that turns red or deep purple when ripe. The spines on the skin are generally shorter and less dense than those of the rambutan.

Interesting Facts About Pulasan:

1. Close Cousin to Rambutan: The pulasan fruit is a close relative of the rambutan and lychee, sharing a similar outer appearance and flavor profile. However, pulasan stands out for its softer, jelly-like flesh, which is sweeter and more aromatic than rambutan. The fruit’s flavor is often described as a more pronounced, syrupy sweetness, making it a favorite for those with a sweet tooth​
2. Twist to Open: The word “pulasan” is derived from the Malay word “pulas,” meaning “to twist.” This name comes from the method used to open the fruit. Instead of using a knife or fingernails to peel the skin, as with rambutan, you twist the pulasan’s outer layer to reveal the juicy interior​
3. Pulasan trees can grow up to 36 meters tall in their natural rainforest habitats, are primarily cultivated in tropical climates like Malaysia and Indonesia. They are generally grown in well-drained soil and require careful propagation methods, such as grafting, air-layering, and seedlings, to ensure healthy growth and high-quality fruit production
4. Unique Flavor: Pulasan’s flavor is often likened to a combination of rambutan and lychee but with an intensified sweetness and juiciness. It has subtle floral and fruity notes, making it perfect for those who enjoy tropical flavors. The fruit’s taste can also vary slightly depending on the ripeness and variety​
