Native to southern Brazil, passion fruit is usually purple or yellow in color and contains a sweet floral flavor that is similar to guava. In the United States, passion fruit is grown in Hawaii, Florida and California, and is an excellent source of iron, calcium and vitamins A and C. Though delicious to eat right out of the rind, passion fruit is mostly used to make drinks and sauces; fresh passion fruit juice is quite a treat and very simple to make.
Cut three passion fruits in half and scoop out their pulp. Place the pulp into a blender.
Add 4 ½ cups water to the fruit in the blender.
Place a lid on the blender and mix until the contents are smooth.
Pour the juice into tall glasses filled with ice.
