Rambutan is a tropical fruit native to Southeast Asia, closely related to the lychee. It has a distinctive appearance with a round shape, covered in a thick, hairy red or yellow skin. The outer spines give it a unique, spiky look. When peeled, the flesh of the rambutan is translucent and juicy, similar in texture to that of a lychee. It has a sweet, mildly acidic flavor that can be quite refreshing. The fruit contains a single seed in the center, which is not edible. Rambutan is often enjoyed fresh, but it can also be used in desserts, salads, and beverages. It's also rich in vitamins and minerals, making it a nutritious snack option.
