Passion fruit syrup is a sweet non-alcoholic syrup flavored with passion fruit, adding tropical flavor, sweetness and color.
Sugar leads here and the fruit follows, which is the opposite of the purée: syrup sweetens a drink and flavors it, while purée sours it and thickens it. The standard measure is 15 ml, dropping to 5–8 where the drink already has sugar elsewhere. That makes it easy in a tiki build with a lot of moving parts, and it means the recipe still needs its lime. Rum and tequila suit it, and vanilla rounds it off — the same partners the fresh purée wants, with the sugar already in.
Make your own: mix equal parts passion fruit purée or pulp with 1:1 sugar syrup, and use it in the same amount. A passion fruit liqueur such as Passoã also works one for one, but the drink comes out less sweet and slightly stronger. Plain sugar syrup keeps the sweetness but loses the fruit.
Passion fruit purée
Fruit with little or no added sugar: it adds acidity and body, but on its own it will not sweeten the drink.
Passion fruit nectar
A juice drink sold in cartons, thin and lightly sweetened: it dilutes a drink more than it sweetens it.
Commercial keeps for months sealed and wants the fridge once open. Homemade on fresh fruit keeps a couple of weeks refrigerated. Seeds left in will not spoil it and will cloud it.
