Passion fruit purée is a thick fruit base of strained passion-fruit pulp.
It sours as much as it flavors, which is unusual for a purée, so a swap usually means adding citrus back. Body is the other half: a juice or a syrup leaves the sour thin and the foam flat.
Passion fruit juice
The pressed liquid without the pulp. It will sharpen and flavor a drink and will not thicken it, and both words turn up on both labels — so a purée recipe made on juice comes out thin.
Passion fruit pulp with seeds
Straight from the fruit, seeds included, and the seeds are edible and crunch, which some drinks want and a shaken sour does not.
Fresh keeps a few days refrigerated and freezes cleanly in portions. Commercial keeps to its date and wants the fridge once open. Freeze it in an ice tray if it goes slowly, since a thawed and refrozen tub separates.
