Passion fruit is the tropical fruit of Passiflora edulis, its shell packed with seeds each wrapped in a sac of tart, aromatic juice.
Most recipes take one or two fruits. Scoop the seeds and pulp into the shaker or the glass for texture and aroma. Or strain the juice and use it to sour a drink, alongside or instead of citrus. It is the fruit in the Pornstar Martini.
Frozen passion fruit purée
The easiest swap, at roughly 15 ml per fruit. Some purées are sweetened: with those, any syrup can drop by about a third of a barspoon per fruit.
Yellow and purple passion fruit
The yellow fruit is larger and more acidic. A drink built for yellow comes out a little sweeter on purple.
Works only where it can replace sugar syrup. The flavor comes through, but the tartness and seeds do not, so add a little lime.
Granadilla
A poor fit. The pulp is milder and less acidic, so the drink turns sweeter and flatter.
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.
