Passion fruit is widely cultivated in tropical climates around the world, but the purple variety is native to such South American countries as Equador, Colombia, Peru and Brazil. It is a good source of vitamins A and C, potassium and iron. The seeds of fresh passion fruit are loaded with dietary fiber.
Passion fruit is found in many varieties, though there are two main ones: yellow and purple. The yellow variety is most often used for juice processing, while the purple is more commonly sold fresh. Purple passion fruit is less acidic with a richer flavor and higher juice content than the yellow.
Passion fruit is similar in make-up to a pomegranate. In fact the Spanish word for passion fruit is “granadilla,” which means "little pomegranate". Passion fruit is quite small, usually less than three inches wide. It has a very tough, brittle and wrinkled rind, inside of which are membranous sacs containing juice and numerous small, pitted seeds. The fruit can be eaten fresh but is usually strained to separate the juice from the seeds. Passion fruit is a wonderful complement to fruit juice blends because it is pulp-free and has a delicious, uniquely tart flavor that does not overpower the other ingredients in the blend.
