Rambutan comes from the Malay word rambut which means hair. These red fruits indeed do look like hairy versions of lychees. To eat, either peel away the skin or make a score with a knife and pull the skin apart. The white fleshy fruit is firm and juicy with a seed in the middle. It is best enjoyed fresh though can be used in a fruit salad or made into a jam.
Canned version or lychees
