Native to Brazil, Paraguay and Northern Argentina, passion fruit is so-called because it is a vine species of passion flower, also known as the 'purple granadilla' in South Africa. Both the seeds and the pulp are used in salads and puddings such as cheesecake and pavlova. Passion fruit is also delicious in drinks, jellies and mousses.
