1. Rambutan
Although it looks like a kids’ toy from the ‘90s, the rambutan is actually edible. To open a rambutan, cup it in your hands and find a groove between the spikes with your thumbs. Push downwards and then outwards to prise it apart. Once through the fuzzy outer shell you’ll find a glistening lychee-like fruit. Pop it whole in your mouth but make sure you don’t eat the seed.
