Longan

What Is Longan?

Longan (Dimocarpus longan) is a small tropical fruit native to Southeast Asia and China, a close relative of lychee and rambutan. It is known for its thin, light brown, smooth skin; the name "dragon eye" comes from its seed appearing embedded in the flesh like an eye.

Beneath the skin is a translucent, whitish, juicy, sweet flesh with a glossy black, inedible seed at its center. It can be eaten fresh, and is also used dried (known in Chinese cuisine as "dried longan").
