Passion fruit is the tropical fruit of Passiflora edulis, its shell packed with seeds each wrapped in a sac of tart, aromatic juice.
Nothing else gives the musky-tropical flavor, so a drink built on it needs the fruit itself in some form. Where the pulp is there for texture rather than flavor, another seeded tropical fruit will do.
Purée and concentrate
They come without seeds, and sugar is more often already in them — so the drink needs less of its own. Professional purée can be unsweetened too; the pack says which.
Yellow vs. purple passion fruit
The yellow fruit is bigger and sharper, the purple smaller and sweeter. One for the other shifts the sweet-sour balance enough to notice: on purple, pull back about a barspoon of syrup.
Granadilla / giant granadilla
Other Passiflora species sold as granadilla or sweet granadilla are milder and sweeter — related but distinct fruits, not passion fruit.
A smooth, hard fruit is unripe and ripens at room temperature in three to five days. A ripe one has wrinkled skin that is not dried out, and it feels heavy for its size. The pulp freezes well, so a glut goes into an ice tray and comes out by the cube.
