This fruit is called Longan/Mata Kuching (cat's eyes) in Malaysia. This fruit is called such because when it is shelled, resembles an eyeball (a black seed shows through the translucent flesh). The seed of this fruit is small, round and hard and of an enamel-like black colour. The flesh of this fruit is easily available by squeezing the fruit our of its shell.
This fruit is available everywhere around Malaysia and we have drinks made from it as well.
