Passion fruit is the edible fruit of the passion flower. Spanish explorers coined the name passion fruit in honor of the passion of Christ. For them, the appearance of the passion flower symbolized many Christian beliefs. Passion fruit grows on a vine in its native tropical and subtropical regions. Commercially, it’s grown in Brazil, the Caribbean, Australia, Africa and some areas of the southern United States. Because of its beautiful flower and the high demand for the fruit, passion fruit is successfully cultivated in native as well as non-native areas. There are two types of passion fruit: purple passion fruit and yellow passion fruit. They are different in appearance but taste the same. The former one is about the size of a large egg, oval shaped with a purple-brown skin. The latter one is a bit larger, round and about the size of an orange. This type is bright yellow on the outside. Both contain a jelly-like pulp inside with hundreds of small black seeds. Passion fruit is popular in gourmet cooking. It is used in many desserts, such as passion fruit mango mousse and passion fruit brulée. Some jams are made of passion fruit. Passion fruit is also used in main dishes, such as lobster with passion fruit butter sauce. Juice, punch, liqueurs and cocktails have a tropical flair when made with it.
