Longan

What Is Longan?

Longan (Dimocarpus longan) is a small tropical fruit native to Southeast Asia and China and closely related to lychee and rambutan. It is known for its thin, smooth, light-brown skin; the name “dragon eye” comes from the seed, which looks like an eye embedded in the flesh.

Beneath the skin is translucent, whitish, juicy, sweet flesh with a shiny black, inedible seed in the center. Longan can be eaten fresh or dried; in Chinese cuisine, it is also used as dried longan fruit.
