Passion fruit is an egg-shaped tropical fruit that is also called a purple granadilla, the passion fruit has a brittle, wrinkled purple-brown rind enclosing flesh-covered seeds, something like a pomegranate (granadilla means "little pomegranate" in Spanish).
The seeds are edible so you can eat the orange pulp straight from the shell. Passion fruit is more commonly sieved and its highly aromatic pulp and juice are used as a flavoring for beverages and sauces. The pulp has an intense aromatic flavor, while the texture is jelly-like and watery. The flavor is likened to guava.
