This is a Granadilla. It looks like a yellow passionfruit. But it's not. Same family though. The granadilla is less tangy and more sweet and somehow sherbet-y. Popping each of the little pips in between your teeth is like bubble-wrap for your mouth! They have no bitterness at all and it is highly satisfying. The seeds and pulp live inside a white fibrous sack that you tear apart to access the sweet goodness. The outside skin is kindof crisp and cracks like an eggshell when you tap it into, say, your head.

These are one of my most favourite of the myriad of tropical fruits available in Cartagena. Whilst they don't tend to be sold by the street fruit vendors, you'll find them at almost any supermarket (exito, olimpica, carrefour etc) at around 4,000 COP/kilo.

Now, here's some virtual bubble wrap for you to play with!
