About the Longan

The longan, also known as Dragon Eyes, is a tropical and subtropical tree with evergreen leaves identifiable by their large size and green colour. This tree can grow to more than 60 ft (20 m). It is similar to the lychee tree in appearance, but more cold-tolerant. Fruit leaves are burgundy red-coloured, turning into a dark green shade in time. Flowers are yellow and the extracted honey can be really sweet.

The fruit grows in oval-shaped trusses. The skin is smooth, thin and orange-coloured, turning into brown just one day after picked. The fruit is covered with little bulges, but less protruding than lychee’s.

The flesh is as aromatic as lychee’s. It is translucent white, juicy and sweet, with a nice, but slightly acid taste and a nutty flavour. The flesh surrounds a round, black-and-bright seed with a white spot, giving it an eye-like appearance. The seed size depends on the fruit variety.

How to preserve and consume longans

Longans are less perishable than lychees because they have more firm husks. The ripe fruit can be refrigerated so it can be consumed for several days. The best way to preserve this fruit is inside a perforated bag in the fridge. The husk is thinner than lychee’s (hence is easier to peel off) and the seed is not edible.

The fruit is mainly consumed out of hand raw, but it can also be used in salads (both sweet and salty) or accompanying rice and vegetable dishes. Besides, it is relatively easy to can and it is also used as an ingredient in many juices and liquors.
